IPv6 Support for EC2 Instances in Virtual Private Clouds
- axyjo 10y agoFinally! It's been a major deficiency in AWS. Can't wait to see this roll out to us-west-2.
- franksunjin 10y agoIts already out, you can launch a ipv6 instance now
- cperciva 10y agoIt's available in the Ohio region, but not in us-west-2 or any of the other regions.
- loganbertram 10y agoDo they have an official roll-out schedule yet?
- vacri 10y agos/AWS/everywhere but Google/
- profmonocle 10y agoGoogle's public services are fully dual-stack, but Compute Engine doesn't support IPv6 at all.
- vacri 10y agoI was more thinking of the ip6 wall of shame than VPS providers, really... Strange that GCE doesn't support it, given their usage elsewhere.
- djsumdog 10y agoI'm kinda sick of all the AWS posts on here, but I'm trying to be fair since some of them are really interesting. This is one of those that's more of a "about damn time," features that'd I'd care about if I already didn't go with Digital Ocean/Linode instead just because of IPv6 support.
- kinkrtyavimoodh 10y agoThe reason there are all these posts in the last few days is because AWS's conference re:Invent is going right now in Las Vegas, and a lot of these announcements are therefore being made right now.
- harryh 10y agoJust curious but why is IPv6 support such a priority for you that it would be the deciding factor in your choice of hosting provider?
- jsmthrowaway 10y agoIn 2017, one should instead ask why it wouldn't be.
- noahm 10y agoOr, to elaborate a little further, https://www.iab.org/2016/11/07/iab-statement-on-ipv6/ https://www.iab.org/2016/11/07/iab-statement-on-ipv6/
- harryh 10y agoBecause there are many other factors in choosing a hosting provider (price, performance, features, security, scalability, etc). It seems a bit weird that all of these would be less important to someone than IPv6. Though I guess I can imagine that for some businesses it could be hugely important. Was just wondering what OPs business was that it became an overriding priority.

- cherioo 10y agoI find it interesting that this didn't make into the keynote. Is the actual interest really low?
- toomuchtodo 10y agoMost production environments terminate on Cloudfront endpoints (or other CDNs) or ELBs/ALBs; not much need for IPv6 to individual instances (which can use IPv4 internally).
- zonknz 10y agoThat's my thinking as well. Surely behind the edge is all implementation and should be hidden? The only appreciable benefit i can see right now is that everything moves back to be a routable internet, no more NAT / nat scaling issues for EC2's sending large quantities of data directly to the public internet?
- Aoreias 10y agoVPC ELBs and ALBs don't support ipv6 though. Presumably this is the first step to adding that support, although it's still not available even in the new ipv6 VPCs.
- zippergz 10y agoThey just announced during the ELB session that ALBs will be supporting full IPv6 also.
- bjeanes 10y agoThe biggest advantage I see (which is heavily coloured by the use cases I faced at Heroku on the Add-ons team) is being able to peer many VPCs without gymnastics to avoid IP range clashes and routing issues. I haven't looked at AWS' IVv6 announcement in enough detail to know if it addresses this head on, but I always looked forward to IPv6 as an avenue to making that kind of work much more straight forward.

- fidget 10y ago8 IPs per instance, max :/
- Dobbs 10y agoThis honestly doesn't surprise me. Adding an infinite number of IPs is one way bot writers get around rate limits. I've done it before when I worked for a company that made a facebook/myspace/etc crawler.
- chipperyman573 10y agoOut of curiosity, why does Amazon consider it their responsibility to prevent that? I'm personally glad that they do, but bots use resources, which is good for Amazon (money in their pocket), and as far as I know Amazon doesn't have anything it wants to protect from bots (at least, anything that would be heavily limited by IP).
- bjeanes 10y agoWell, one explanation might be the reputation of their IP ranges. Already, payment processors and some mail servers will give extra scrutiny to IP ranges belonging to AWS. If AWS is made attractive to that audience and damage is done to the reputation (in various systems) of those IP ranges, their offering becomes less compelling to all customer demographics.
- openasocket 10y agoFrom a rational self-interest standpoint, bots tend to get their IP addresses blocked by whoever they're targeting. Which means the Amazon IP address space gets on threat lists and block lists. The bot owners can just generate new instances with new IP addresses, and then some legitimate customer spins up an instance and gets their address, and wind up on blocked. The bots keep going until various services decide to just block all of Amazon's space, the same way they would for Tor exit nodes or other things associated with shady activity.

- josho 10y agoIs there a succinct developer/administrators guide to IPv6? I recently discovered my home IP is ipv6 and have started to realize that it is more than just a larger address range. e.g. arp is replaced with ndp. While I haven't yet found a guide that has more depth than the very basics, but isn't a full on Cisco manual.
- axyjo 10y agoHE's IPv6 training guide is pretty good -- https://ipv6.he.net/certification/ https://ipv6.he.net/certification/
- pilif 10y agoAnd you can get an awesome T-Shirt if you complete it. I wear mine with pride, mainly because in the process of doing it, I nagged our business ISP into properly supporting reverse delegations
- lucb1e 10y agoI tried writing one a few years ago when I got IPv6 at home: http://lucb1e.com/!ipv6 http://lucb1e.com/!ipv6
- zbjornson 10y agoPardon my ignorance, but why is this needed? I've seen dozens of "+1s" for ipv6 on both AWS and GCP, but no one says why really. Is there hardware out there on the public internet that cannot communicate over ipv4 already?
- Mythanar 10y agoMost of it can't, actually. Rather, using the words in the question in their strict meaning, most of the hardware out there is not on the "public internet", it is behind NAT. You can argue that behind NAT there is still IPv4 connectivity with public internet, but it is actually closer to proxying (i.e. having some device talk to internet on your behalf) than to routing (i.e. have some device pass your packets on). Long story short, there is (for a long time already), no IPv4 public internet. There is IPv4 public interconnect between millions of isolated IPv4 islands. And a lot of hacks and shady engineering to make packets traverse from interconnect to islands and back.
- zbjornson 10y agoBut if that exists, why should I as someone running on EC2 care if I can use IPv6 natively or have to make use of such proxying/routing?
- toast0 10y agoI don't know enough AWS to understand the announcement, but if your servers and your clients can speak IPv6 and you can skip al the NAT, you don't have to debug NAT problems.
- sigjuice 10y agoWe probably won't ever be rid of NAT. The likes of Cisco, who thrive on making things enterprisey and needlessly complicated will definitely be peddling IPv6 NAT soon, if they aren't already doing it.
- 10y ago
- lyonlim 10y agoI believe this doesn't mean there's IPv6 support for ELBs in a VPC yet. We unknowingly enabled dualstack configuration on Route 53 some time back and this led to users on devices which prioritised IPv6 over IPv4 to fail to connect.
- zippergz 10y agoThere will be very soon. They announced it today during a session on ELB.
- dispose13432 10y agoHonestly, can someone explain why it took so long? I mean, you can get IPv6 on a bunch of low-end budget VPSs. Why couldn't Amazon do it? And why cant GCE do it? Is it a lot of work?
- rb2k_ 10y agoA colleague of mine gave a talk at SRECon about the fun world of IPv6 provisioning: https://www.youtube.com/watch?v=0gjuVhph520 https://www.youtube.com/watch?v=0gjuVhph520 Granted, that isn't necessarily a pre-requisite for going dual stack (aka: just attaching a v6 address to a machine), but it shows the fun problems you run into.
- vbernat 10y agoThe more layers you have, the more time you need to convert all of them to IPv6 (from network to all the applications). IPv6 implementations of various things is always less complete than their IPv4 counterpart. Notably, even low-level stuff may still be difficult to make with IPv6. For example, Linux supports IP equal-cost multipath routing for IPv6 since 2012. Quagga, a popular routing daemon, still doesn't support that. BIRD, another open-source routing daemon, just got partial support for it this year. If your network is relying on this, it's an additional burden to deploy IPv6.
- faitswulff 10y agoI have to wonder if Amazon started releasing all this product news to cover up the fact that one of their employees jumped off the company building in an apparent suicide attempt: https://news.ycombinator.com/item?id=13059565 https://news.ycombinator.com/item?id=13059565
- sudhirj 10y agoThe AWS reinvent conference is going on, which is their annual developer conference. So probably just a coincidence. Each announcement has a stage announcement and planned sessions as well.
- secure 10y agoI’m not an AWS user, so the “Virtual Private Cloud” caveat confuses me. If I just click an EC2 instance, will that be in a “Virtual Private Cloud” or not? Also, are these IPv6 addresses publically reachable or not?
- sepeth 10y agoThey are public. When you create an AWS account, you will have a default VPC (this wasn't the case with the classic EC2), and when launching an instance, if you don't specify anything else, the instance you launch will be in the default VPC.
- irishsultan 10y agoIf you're not an AWS user yet then any EC2 instance you create (if you ever decide to become an AWS user) will be in a Virtual Private Cloud, either one you create yourself or the default VPC associated with your account. Only older accounts (from before december 2013) have the ability to create EC2 instances that aren't in a VPC.

- vhost- 10y agoThe state of IPv6 remains sad and depressing. I just switched to centurylink fiber from comcast and I still don't have an IPv6 address. I have the option, but I have to pay for it, which seems totally backwards to me. Sure, I will pay for a static IPv4 address if I need it because I understand that they are few and far between by now. But you can't just give me one v6? Basically I have a fiber connection in the US, which on it's own is pretty mindblowing, but no IPv6 address...
