IMO the major thing holding back IPv6 on the web is amazon. A huge proportion of services are hosted on AWS, and the lack of IPv6 addressing of instances cannot be forgiven.

      The worst part about reddit in that case is that they use cloudflare which could be a 1 click update to ipv6. Previously they have stated that internal systems (spam, court orders, reporting) are holding them back from the change.

        You know, Cloudflare gets a lot of shit around here for being a centralizing entity in a decentralized Internet (sometimes justifiably), but they've done a hell of a lot to push forward needed changes in the Internet infrastructure. Often at little benefit to themselves.

        Both Microsoft and Apple's www sites use Akamai's CDN, via a cname to a CNAME to something in akamaiedge.net, which support ipv6. The apex record of a domain (that is, the root record, microsoft.com or apple.com) cannot be a CNAME, it can only have an A, NS, MX or TXT record. A records make dynamic infrastructure hard, because they require API coordination between your DNS provider and your CDN. So Microsoft and apple host their own apex domain records via A records to static IPs in their own IP blocks, and have these servers issue a permanent http redirect to www.

      With poor adoption rate of IPv6 persists in China, half of those listed (taobao, tmall, baidu, hao123, qq, youku, sina, weibo, etc.) just won't change in near future.
      - ryao 10y ago
        I am visiting China. It seems impossible to get an IPv6 address from either China Telecom (the ASN lacks IPv6 peering) or a datacentdr within China. Sending traffic to a VM in South Korea has similarly had the issue where I cannot find any VMs with IPv6 support, although most have terrible latencies.

      At a cursory glance, it seems that Google or Google-owned sites make up a majority of the IPv6-enabled sites. Seems to me the numbers would be a lot lower without Google's work.

    - StavrosK 10y ago
      "Getting?" I set up some CloudFront instances (or whatever they call them) a month ago and it had an IPv6 checkbox (which was unchecked by default, for some reason), but it seems to have been working fine ever since.

    ELBs support ipv6 as well
    - kalleboo 10y ago
      Only EC2-Classic ELBs do, which is only available to users who signed up for AWS before Dec 2013 (and doesn't support all the new VPC goodness)
- fulafel 10y ago
  IPv6 and a return to end-to-end addressing isn't really aligned with the AWS style of proprietary platform lock-in.
  - icedchai 10y ago
    This makes no sense. AWS can give you IPv4 elastic IPs, which provide end-to-end addressing on IPv4. IPv6 will be no different in this regard. "End-to-end addressing" is typically an end user issue, where end users use NAT. In the early days of the internet, nobody used NAT.
    - fulafel 10y ago
      AWS encourages you to use VPCs for service-internal addressing. Yes, you can rent "elastic IPs", but in the AWS mindset they are special and to be used only for NATing Internet endpoints to your services. It's based on end-to-end addressing being special and a scarce resource. This is compatible with the traditional corporate intranet style of thinking, but it's also in the opposite of internet end-to-end addressing and they are in no hurry to change it.
      - dastbe 10y ago
        ipv6 has a provision for locally routable addresses, because yes publicly routable addresses should be special. They should just also be free.
        fulafel 10y ago
        Link-local addresses are not routable and are not meant for application use, they're just for low level things like neighbour discovery and router advertisements (analogous to IPv4 ARP/DHCP). There's also ULA that can be used for non-internet connected networks and some other special scenarios, but it would be a bad idea (and against recommended practice) to use them to port your RFC1918 addressing to IPv6.
- danyork 10y ago
  The good news is that Amazon has been slowly rolling out IPv6 support across various AWS services (ex. S3, CloudFront). Once they support IPv6 on EC2, though, that will be the big breakthrough!
  - yuvadam 10y ago
    Not to mention Route 53, which can serve AAAA records, but still has no IPv6 nameservers.

- cm2187 10y ago
  I'd say ISPs to start with. In the UK, BT still hasn't rolled out IPv6. Neither has vodafone. Also I have servers in colocation with two datacenters, and for both I had to ask to the support to get an IPv6 range. We are very far from IPv6 becoming a standard feature.
  - lisivka 10y ago
    It's time to switch HN to be IPv6 only forum, so 100% of HN'ers will be on IPv6 almost instantly. ;-)
  - Latty 10y ago
    > I'd say ISPs to start with. In the UK, BT still hasn't rolled out IPv6. BT have at least partially rolled out support, as I have a v6 allocation on a BT broadband service.
    - cm2187 10y ago
      I have read I can get it by upgrading to the very latest version of BT Home Hub (I am using 5). I ordered it yesterday. But my current Home Hub 5 is compatible, and I still don't have IPv6.
      - jburgess777 10y ago
        It looks like you would have got support on your existing device soon. A recent BT presentation says: "[IPv6 support] Home Hubs 4 and 5 support from early 2017" http://www.ipv6.org.uk/wp-content/uploads/2016/11/UKIPv6Council-2016-BT-Update-Mcrae.pdf http://www.ipv6.org.uk/wp-content/uploads/2016/11/UKIPv6Coun...

        Actually I just received my new router and I now have IPv6!
  - the8472 10y ago
    That varies strongly by country[0]. My home ISP for example does DS-Lite and last week their AFTR was overloaded. So ipv4 was almost unusable while v6 worked fine. So temporarily I was already living in a post-v4 world.

executesorder66 10y ago
I check the google stats[0] on ipv6 adoption every few months. Last time I checked it was barely 9% an now it's on 15% ! I would have never thought we'd get this far this fast. Looks like the switchover is actually going to happen. [0]https://www.google.com/intl/en/ipv6/statistics.html https://www.google.com/intl/en/ipv6/statistics.html
- tomschlick 10y ago
  Looks like the US is up to 30% now! I suspect mobile traffic is largely driving this as all the major carriers are moving to ipv6 only and proxy an ipv4 address when needed.
- vishbar 10y ago
  Really interesting how it spikes on weekends! I wonder if this is because more home broadband connections are ipv6-enabled compared to businesses?
  - executesorder66 10y ago
    I guess it's hobbyists who's normal internet connection is ipv4, but on the weekend they have time to dick around with ipv6 devices and connections.
    - mSparks 10y ago
      possible i guess do we see something similar with .onion addresses? ive found it much more reliable and secure to give devices i want access to from anywhere a .onion address rather than a ipv6 one. secure by design rather than plaintext insecure and only works on some internet connections occasionally by design nightmare that is ipv6.
    - selectodude 10y ago
      Comcast and Verizon Wireless rolled out IPv6 years ago, and resolves IPv6 addresses first by default. Nobody is dicking around, it's just transparent.
Arnt 10y ago
I noticed the other day that IPv6 growth is slowing down, as Google measures it. Its access share used to double every ten or eleven months, now it doubles more slowly, and seems likely to reach 20% only in 2017 instead of this year, and if it goes on as in the recent months, 30% in 2018 instead of in 2017. At a guess, many of most competent ISPs have done their thing and now we're seeing the more sluggish middle. Or? Comments?
- Ambroos 10y ago
  In Belgium we're up to 49.5% of Google traffic over IPv6, which is pretty impressive. All major ISP's have IPv6 enabled in a dual-stack setup right now. This works because almost all of them provide an all-in-one modem/router/access point, all remotely managed, so it's easy to just flick a switch on the ISP end and magically have everything go over IPv6. What's holding back further progress is mostly people with their own NAT routers/DHCP that's not set up for IPv6, or company networks where the transition isn't planned. That's going to change very, very slowly indeed.
- lmm 10y ago
  IPv6 was always going to be an S-curve. My guess is we'll see switchover at about the same rate up to 80%-90%, and then a long tail.
- eb0la 10y ago
  If I remember well at least 2-3 years ago it was complicated to measure IPv6 usage on a high-end router, and that was tied to billing. Every vendor (Cisco/Juniper/Alcatel/Huawei) had a different way to do it and since B2B billing depended on it IPv6 adoption was not as easy as expected.
  - woah 10y ago
    What was complicated about it?
    - eb0la 10y ago
      Every vendor had a different way to measure how much octets went through an interface on IPv6 using SNMP. And the standard MIB (management information base) for SNMP only gave you IPv4 traffic. So, if you wanted to measure the traffic you interchange with a third party on IPv6 you had to be tied to a specific way of doing in (some had private or experimental MIBs for that, in other cases you had to move the data through a tunnel and measure traffic inside the tunnel minus overhead.). Very easy to make mistakes specially if there is a problem with the traffic late at night and somebody forgets to put you in the loop.

Topically, here are the minutes from the latest UK IPV6 Council meeting: http://www.ipv6.org.uk/2016/08/31/ipv6-council-meeting-october-2016/ http://www.ipv6.org.uk/2016/08/31/ipv6-council-meeting-octob... Sky and BT both looking good, sadly Virgin didn't present this year.
NKCSS 10y ago
Better late than never I guess, but come on... IPv6 is nearly 20 years old in 2 years...
Spooky23 10y ago
I've not run into a problem solved by IPv6. There's no incentive for ISPs to provide good service, so they can just follow the mobile carrier route and nat/proxy when exhaustion becomes an issue. As other countries go IPv6, more IPv4 addresses become available for the big cloud providers.
- ryao 10y ago
  I get better peering though the HE tunnel broker than I get on IPv4. :)
  - liotier 10y ago
    Especially to exotic destinations and to services which my ISP feels like choking a little (such as Youtube)...
- proactivesvcs 10y ago
  I run into NAT almost every single day. It wastes time, breaks things, consumes router resources, rules out certain technologies/products/services and duplicates so much work it's just unreal.
  - _red 10y ago
    >consumes router resources Thats a weird claim to make against IPv4. Grab a calculator and see how much memory is required by a IPv6 /64 address space.
    - ncw33 10y ago
      Not much! Just a few bytes for each packet. Running a NAT service requires a big table of all the active connections, ie. it's stateful - IPv6 with no NAT needs no per-connection state in the router so that's a big space-saving.
      - _red 10y ago
        So you don't want stateful inspection on your private LAN router? Its ok for every hacker to portscan the 100's of IoT devices in your house? You're a very trusting fellow.
fs111 10y ago

cjensen 10y ago
We have a product that uses ipv6 for inter-server communications. We've since learned that most major corporations routinely disable ipv6 on every computer. Not helping.
- danudey 10y ago
  Heard a "funny" story about Facebook switching over to pure IPv6 and their issues dealing with largely untested IPv6 implementations. For example, switches which, when presented with an IPv6 BGP route while they don't have IPv6 configured, crash. Apparently they took down an entire data centre full of rack switches finding that out. My second-favorite problem, after that was solved, was developers constantly using IPv4-only code. Their eventual solution was to just disable IPv4 entirely so that anyone committing IPv4-only code was committing broken code. It's amazing how much work it takes to bring people into the future.
  - eb0la 10y ago
    Very "funny", but that kind of crashes happened more than you imagine.. in telcos. Usually the problem is memory. A machine with full routing enabled needs much more memory for IPv6 than for IPv4 and when routers run out of memory they just crash, reboot, and start again...
    - CountSessine 10y ago
      Usually the problem is memory. A machine with full routing enabled needs much more memory for IPv6 than for IPv4 Interesting - why? I would have thought that routing tables for ipv6 would be a fraction of the size of their ipv4 equivalents. Am I wrong? Or is this just sloppy programming on the part of those switch programmers?
Keverw 10y ago
I hope we don't have IPv6 only protocols and sites anytime soon. My cable company still is not supporting IPv6... It seems like something a major American ISP would of done by now.
- virtuallynathan 10y ago
  Which one?
  - Keverw 10y ago
    I used http://test-ipv6.com/ http://test-ipv6.com/ to run the test. Your Internet Service Provider (ISP) appears to be SCRR-10796 - Time Warner Cable Internet LLC, US I'm in Ohio.
    - wtallis 10y ago

Your issue is site-specific; most likely your modem is outdated, but your router may also be configured to not try to acquire a block of IPv6 addresses.
      - Keverw 10y ago
        Interesting. No communication from them. I figured this is the sorta thing they'd mass contact people about to update. I remember asking the installer about 3 years ago about it. He said I'd have it as soon as they turn it on at the central office... I'm not really too worried about it yet as it's not a problem really yet. I hate talking to support people. I went to the IPv6 page and it's not showing a V6 IP Address http://screencast.com/t/Xuq4VOfnS http://screencast.com/t/Xuq4VOfnS but the Dynamic page for IPv4 displays it in those text boxes(editing is disabled on them even though they look like inputs. A bit confusing UX if just looking at the image) So it appears my firmware has it... strange. This is on the modem itself, not the router as it's a all in one. Just found this: http://forums.timewarnercable.com/t5/IPv6/Not-getting-IPv6-Address/td-p/113119/page/2 http://forums.timewarnercable.com/t5/IPv6/Not-getting-IPv6-A... from two months ago "I got someone from Tier 3 on the phone and he told me it was not available yet in my area." so hmm, sounds like some areas might be last to get it then.
djhworld 10y ago
I'm wondering what will happen when ISPs start doling out IPv6 addresses, will every customer get a unique, static IPv6 address? Right now my ISP (BT) gives you an IPv4 address, but it's dynamic. They charge extra for a static IP
- jburgess777 10y ago
  I don't have an answer to your question but the latest news from BT is: "All BT broadband lines support IPv6 with a compatible router, except IPstream connections" http://www.ipv6.org.uk/wp-content/uploads/2016/11/UKIPv6Council-2016-BT-Update-Mcrae.pdf http://www.ipv6.org.uk/wp-content/uploads/2016/11/UKIPv6Coun...
pc2g4d 10y ago
This is telling organizations developing standards to basically pretend IPv4 doesn't exist and is no longer in use. At least that's how I read it. Seems a bit premature.

Yes, you can rent "elastic IPs", but in the AWS mindset they are special and to be used only for NATing Internet endpoints to your services. It's based on end-to-end addressing being special and a scarce resource. This is compatible with the traditional corporate intranet style of thinking, but it's also in the opposite of internet end-to-end addressing and they are in no hurry to change it.

      ipv6 has a provision for locally routable addresses, because yes publicly routable addresses should be special. They should just also be free.
      - fulafel 10y ago
        Link-local addresses are not routable and are not meant for application use, they're just for low level things like neighbour discovery and router advertisements (analogous to IPv4 ARP/DHCP). There's also ULA that can be used for non-internet connected networks and some other special scenarios, but it would be a bad idea (and against recommended practice) to use them to port your RFC1918 addressing to IPv6.

The good news is that Amazon has been slowly rolling out IPv6 support across various AWS services (ex. S3, CloudFront). Once they support IPv6 on EC2, though, that will be the big breakthrough!
- yuvadam 10y ago
  Not to mention Route 53, which can serve AAAA records, but still has no IPv6 nameservers.

I'd say ISPs to start with. In the UK, BT still hasn't rolled out IPv6. Neither has vodafone. Also I have servers in colocation with two datacenters, and for both I had to ask to the support to get an IPv6 range. We are very far from IPv6 becoming a standard feature.
- lisivka 10y ago
  It's time to switch HN to be IPv6 only forum, so 100% of HN'ers will be on IPv6 almost instantly. ;-)

  > I'd say ISPs to start with. In the UK, BT still hasn't rolled out IPv6. BT have at least partially rolled out support, as I have a v6 allocation on a BT broadband service.
  - cm2187 10y ago
    I have read I can get it by upgrading to the very latest version of BT Home Hub (I am using 5). I ordered it yesterday. But my current Home Hub 5 is compatible, and I still don't have IPv6.
    - jburgess777 10y ago
      It looks like you would have got support on your existing device soon. A recent BT presentation says: "[IPv6 support] Home Hubs 4 and 5 support from early 2017" http://www.ipv6.org.uk/wp-content/uploads/2016/11/UKIPv6Council-2016-BT-Update-Mcrae.pdf http://www.ipv6.org.uk/wp-content/uploads/2016/11/UKIPv6Coun...

        Actually I just received my new router and I now have IPv6!
- the8472 10y ago
  That varies strongly by country[0]. My home ISP for example does DS-Lite and last week their AFTR was overloaded. So ipv4 was almost unusable while v6 worked fine. So temporarily I was already living in a post-v4 world.

I check the google stats[0] on ipv6 adoption every few months. Last time I checked it was barely 9% an now it's on 15% ! I would have never thought we'd get this far this fast. Looks like the switchover is actually going to happen. [0]https://www.google.com/intl/en/ipv6/statistics.html https://www.google.com/intl/en/ipv6/statistics.html

tomschlick 10y ago
Looks like the US is up to 30% now! I suspect mobile traffic is largely driving this as all the major carriers are moving to ipv6 only and proxy an ipv4 address when needed.
vishbar 10y ago
Really interesting how it spikes on weekends! I wonder if this is because more home broadband connections are ipv6-enabled compared to businesses?
- executesorder66 10y ago
  I guess it's hobbyists who's normal internet connection is ipv4, but on the weekend they have time to dick around with ipv6 devices and connections.
  - mSparks 10y ago
    possible i guess do we see something similar with .onion addresses? ive found it much more reliable and secure to give devices i want access to from anywhere a .onion address rather than a ipv6 one. secure by design rather than plaintext insecure and only works on some internet connections occasionally by design nightmare that is ipv6.
  - selectodude 10y ago
    Comcast and Verizon Wireless rolled out IPv6 years ago, and resolves IPv6 addresses first by default. Nobody is dicking around, it's just transparent.

Arnt 10y ago

I noticed the other day that IPv6 growth is slowing down, as Google measures it. Its access share used to double every ten or eleven months, now it doubles more slowly, and seems likely to reach 20% only in 2017 instead of this year, and if it goes on as in the recent months, 30% in 2018 instead of in 2017. At a guess, many of most competent ISPs have done their thing and now we're seeing the more sluggish middle. Or? Comments?

Ambroos 10y ago
In Belgium we're up to 49.5% of Google traffic over IPv6, which is pretty impressive. All major ISP's have IPv6 enabled in a dual-stack setup right now. This works because almost all of them provide an all-in-one modem/router/access point, all remotely managed, so it's easy to just flick a switch on the ISP end and magically have everything go over IPv6. What's holding back further progress is mostly people with their own NAT routers/DHCP that's not set up for IPv6, or company networks where the transition isn't planned. That's going to change very, very slowly indeed.
lmm 10y ago
IPv6 was always going to be an S-curve. My guess is we'll see switchover at about the same rate up to 80%-90%, and then a long tail.
eb0la 10y ago
If I remember well at least 2-3 years ago it was complicated to measure IPv6 usage on a high-end router, and that was tied to billing. Every vendor (Cisco/Juniper/Alcatel/Huawei) had a different way to do it and since B2B billing depended on it IPv6 adoption was not as easy as expected.
- woah 10y ago
  What was complicated about it?
  - eb0la 10y ago
    Every vendor had a different way to measure how much octets went through an interface on IPv6 using SNMP. And the standard MIB (management information base) for SNMP only gave you IPv4 traffic. So, if you wanted to measure the traffic you interchange with a third party on IPv6 you had to be tied to a specific way of doing in (some had private or experimental MIBs for that, in other cases you had to move the data through a tunnel and measure traffic inside the tunnel minus overhead.). Very easy to make mistakes specially if there is a problem with the traffic late at night and somebody forgets to put you in the loop.

Topically, here are the minutes from the latest UK IPV6 Council meeting: http://www.ipv6.org.uk/2016/08/31/ipv6-council-meeting-october-2016/ http://www.ipv6.org.uk/2016/08/31/ipv6-council-meeting-octob... Sky and BT both looking good, sadly Virgin didn't present this year.

NKCSS 10y ago

Better late than never I guess, but come on... IPv6 is nearly 20 years old in 2 years...

Spooky23 10y ago

I've not run into a problem solved by IPv6. There's no incentive for ISPs to provide good service, so they can just follow the mobile carrier route and nat/proxy when exhaustion becomes an issue. As other countries go IPv6, more IPv4 addresses become available for the big cloud providers.

ryao 10y ago
I get better peering though the HE tunnel broker than I get on IPv4. :)
- liotier 10y ago
  Especially to exotic destinations and to services which my ISP feels like choking a little (such as Youtube)...
proactivesvcs 10y ago
I run into NAT almost every single day. It wastes time, breaks things, consumes router resources, rules out certain technologies/products/services and duplicates so much work it's just unreal.
- _red 10y ago
  >consumes router resources Thats a weird claim to make against IPv4. Grab a calculator and see how much memory is required by a IPv6 /64 address space.
  - ncw33 10y ago
    Not much! Just a few bytes for each packet. Running a NAT service requires a big table of all the active connections, ie. it's stateful - IPv6 with no NAT needs no per-connection state in the router so that's a big space-saving.
    - _red 10y ago
      So you don't want stateful inspection on your private LAN router? Its ok for every hacker to portscan the 100's of IoT devices in your house? You're a very trusting fellow.

fs111 10y ago

and yet news.ycombinator.com is still not IPv6 enabled...

shmerl 10y ago

When will Verizon FiOS enable IPv6?

cjensen 10y ago

We have a product that uses ipv6 for inter-server communications. We've since learned that most major corporations routinely disable ipv6 on every computer. Not helping.

danudey 10y ago
Heard a "funny" story about Facebook switching over to pure IPv6 and their issues dealing with largely untested IPv6 implementations. For example, switches which, when presented with an IPv6 BGP route while they don't have IPv6 configured, crash. Apparently they took down an entire data centre full of rack switches finding that out. My second-favorite problem, after that was solved, was developers constantly using IPv4-only code. Their eventual solution was to just disable IPv4 entirely so that anyone committing IPv4-only code was committing broken code. It's amazing how much work it takes to bring people into the future.
- eb0la 10y ago
  Very "funny", but that kind of crashes happened more than you imagine.. in telcos. Usually the problem is memory. A machine with full routing enabled needs much more memory for IPv6 than for IPv4 and when routers run out of memory they just crash, reboot, and start again...
  - CountSessine 10y ago
    Usually the problem is memory. A machine with full routing enabled needs much more memory for IPv6 than for IPv4 Interesting - why? I would have thought that routing tables for ipv6 would be a fraction of the size of their ipv4 equivalents. Am I wrong? Or is this just sloppy programming on the part of those switch programmers?

Keverw 10y ago

I hope we don't have IPv6 only protocols and sites anytime soon. My cable company still is not supporting IPv6... It seems like something a major American ISP would of done by now.

virtuallynathan 10y ago
Which one?
- Keverw 10y ago
  I used http://test-ipv6.com/ http://test-ipv6.com/ to run the test. Your Internet Service Provider (ISP) appears to be SCRR-10796 - Time Warner Cable Internet LLC, US I'm in Ohio.
  - wtallis 10y ago
    Time Warner Cable provides IPv6: https://www.timewarnercable.com/en/support/faqs/faqs-internet/ipv6/why-don_t-i-have-ipv6-yet-.html https://www.timewarnercable.com/en/support/faqs/faqs-interne... Your issue is site-specific; most likely your modem is outdated, but your router may also be configured to not try to acquire a block of IPv6 addresses.
    - Keverw 10y ago
      Interesting. No communication from them. I figured this is the sorta thing they'd mass contact people about to update. I remember asking the installer about 3 years ago about it. He said I'd have it as soon as they turn it on at the central office... I'm not really too worried about it yet as it's not a problem really yet. I hate talking to support people. I went to the IPv6 page and it's not showing a V6 IP Address http://screencast.com/t/Xuq4VOfnS http://screencast.com/t/Xuq4VOfnS but the Dynamic page for IPv4 displays it in those text boxes(editing is disabled on them even though they look like inputs. A bit confusing UX if just looking at the image) So it appears my firmware has it... strange. This is on the modem itself, not the router as it's a all in one. Just found this: http://forums.timewarnercable.com/t5/IPv6/Not-getting-IPv6-Address/td-p/113119/page/2 http://forums.timewarnercable.com/t5/IPv6/Not-getting-IPv6-A... from two months ago "I got someone from Tier 3 on the phone and he told me it was not available yet in my area." so hmm, sounds like some areas might be last to get it then.

djhworld 10y ago

I'm wondering what will happen when ISPs start doling out IPv6 addresses, will every customer get a unique, static IPv6 address? Right now my ISP (BT) gives you an IPv4 address, but it's dynamic. They charge extra for a static IP

jburgess777 10y ago
I don't have an answer to your question but the latest news from BT is: "All BT broadband lines support IPv6 with a compatible router, except IPstream connections" http://www.ipv6.org.uk/wp-content/uploads/2016/11/UKIPv6Council-2016-BT-Update-Mcrae.pdf http://www.ipv6.org.uk/wp-content/uploads/2016/11/UKIPv6Coun...

pc2g4d 10y ago

This is telling organizations developing standards to basically pretend IPv4 doesn't exist and is no longer in use. At least that's how I read it. Seems a bit premature.
