IPv6 Support for AWS Extended to 15 Regions
- masterleep 10y agoIt's sad that Google Cloud Platform is behind on this.
- doh 10y agoAs I was told recently, IPV6 is not comming anytime soon to GCP (not in next 6 months).
- StreamBright 10y agoI think Google internally uses ipv6 for desktop computers though. I thought they are going to be faster with ipv6 rollout given how much they are investing into SDNs.
- doh 10y agoI think they would make it public if they believe they are scale ready. From my experience working there years ago, one of the first requirements was to be able to scale to any kind of requirements.
- nodesocket 10y agoWhile not a perfect solution, you can use CloudFlare in front of your app/site for full IPv6 support without having to deal with AAAA records and IPv6 support from your origin.
- samhamilton 10y agoYep - thats what we rolled out for our iOS app, CloudFlare IPv4/6 + AWS just IPv4
- Thaxll 10y agoWell most ISP don't support IPv6 so it's really not an issue atm.
- kavok 10y agoMany ISPs in the mobile space are switching to IPv6 aggressively http://www.circleid.com/posts/20090609_verizon_mandates_ipv6_support_for_next_gen_cell_phOnes/ http://www.circleid.com/posts/20090609_verizon_mandates_ipv6... and mobile internet usage is eclipsing traditional formats https://www.comscore.com/Insights/Blog/Number-of-Mobile-Only-Internet-Users-Now-Exceeds-Desktop-Only-in-the-U.S https://www.comscore.com/Insights/Blog/Number-of-Mobile-Only...
- ac29 10y agoThe 2 largest ISPs in my area (and 2 of the largest in the US), AT&T and Comcast, both support IPv6.
- jfoutz 10y agoServers in different regions don't have to do double nat. You may not have this problem, but some people do. And it sucks.
- hueving 10y agoYou might be surprised. Almost every cable company in the US does, so most Internet users in the US could have ipv6. The problem is usually the $50 wireless access point most people bought 5 years ago doesn't pass ipv6 through.
- edwhitesell 10y agoSpectrum (formerly TWC) in Dallas does not. I still run an he.net tunnel on my router. Last time I checked (a few months ago), UVerse in Dallas didn't either.
- hueving 10y agoI wonder if it's a regional thing? A friend of mine has spectrum from Charter (formerly Bresnan in this case) and he gets ipv6.
- Animats 10y agoIt's embarrassing that the cloud providers weren't IPv6-capable from day one. They're new, not legacy systems.
- hossbeast 10y agoEC2 is 10 years old
- robin_reala 10y agoIPv6 is 18 years old.
- spullara 10y agoIPv6 is pointless until we remove IPv4
- StreamBright 10y agoHowever, most of the users of internet were not ipv6 ready until very recently. It is a simply supply and demand question, where nobody wanted to invest in ipv6 infra first. Replacing networking gear for supporting ipv6 is very pricey operation too. I remember having pretty bad issues of having a dual stack in software. One example is when the python resolver library defaulted to ipv6 resolution first for a domain name, and the nxdomain to the AAAA request invalidated the name cache on the servers. When we changed this behaviour to default to ipv4 we saved an insane amount of CPU time. There are lots of issues like this one in a cloud environment, most people are never going to face this though.
- compuguy 10y agoVerizon FIOS and DSL still doesn't provide ipv6 addresses, so we have a ways to go still.
- boulos 10y agoWe're sad about that, too (I work on Google Cloud).
- coderholic 10y agoThis is great news. The reason we support IPv6 lookups but only over IPv4 connections on https://ipinfo.io https://ipinfo.io is because we use AWS with VPC, which hasn't historically supported IPv6. Except many sites/services to add IPv6 now that were previously limited by this.
- nodesocket 10y agoI just came across https://ipinfo.io https://ipinfo.io, great service. I actually use it when hyperlinking IP addresses for a quick way to view GeoIP information. Thanks!
- graystevens 10y agoJust wanted to echo node's comment above - I regularly use ipinfo.io and find it very useful. I'm sure the plethora of other 'IP lookup' sites have very similar data, but your design and layout makes all the difference. Thank you!
- jfoutz 10y agoIPv4 is great, but nat makes things so hard. This sounds wonderful.
- snuxoll 10y agoNAT sucks, but so does a lack of affordable L3 switches that can handle IPv6 routing (not that I'll use that against IPv6, but it's a personal pain point of mine). If I wanted to deploy v6 in my home network I'd literally have to configure my EdgeRouter X on every VLAN in my home network (and as such stuff all IPv6 traffic on my network that crosses subnets into a single 1Gbe connection), since my TP-Link managed switch has no facility to put out a IPv6 RA (even though it supports IPv6 routing, go figure). I'm really digging the age of vendor silicon where most switches just support whatever Broadcom/etc. put into their chips, but man I hope they catch up with IPv6 soon because right now only the big boys (Cisco/Juniper/HP/Dell/etc.) seem to have any hardware with full IPv6 support, and then you're paying a hefty price for the hardware + support contract (assuming you want software updates).
- ramshanker 10y agoHalf the internet shall be available on IPv6 soon now. ;)
- pyvpx 10y agowell, no. now the excuse will shift from AWS doesn't support IPv6 to Kubernetes doesn't support IPv6 :p
- spencerhakim 10y agoUnless something has changed since I just happened to have checked earlier today, VPC ELBs are still IPv4-only. They return AAAA records on the ipv6 and dualstack subdomains like their classic/non-VPC counterparts (which do fully support IPv6), but the ports aren't open on the returned addresses, so it's not very useful. Maybe someone from Amazon can chime in?
- deleted 10y ago[deleted]
- nonane 10y ago+1 on this. Would appreciate someone from Amazon commenting on this. Unfortunately it looks like VPC ELBs are still IPv4 only. They have a link in the article from when they introduced IPv6 for non-VPC ELBs back in 2011. Are VPC ELBs being worked on anymore or are we going to have to move to Application Load Balancers for IPv6 support?
- cherioo 10y agoIf you read the article, you will learn that ALB (new L7 ELB) now supports IPv6.
- deleted 10y ago[deleted]
- spencerhakim 10y ago...I did read the article, what do ALBs have anything to do with what I said? Or are you just assuming that no one needs non-HTTP services running in a VPC load balanced over IPv6?
- paulddraper 10y agoHTTP is the new skinny waist of the internet.
- ploxiln 10y ago
- nodesocket 10y agoCan I enable IPv6 on all instances in a VPC that is already deployed in us-west-1? Does this require stopping and starting all instances?
- ejdyksen 10y agoHere's an outline of the steps you need to take to get things working: http://docs.aws.amazon.com/AmazonVPC/latest/UserGuide/vpc-migrate-ipv6.html http://docs.aws.amazon.com/AmazonVPC/latest/UserGuide/vpc-mi...
- nodesocket 10y agoThanks for linking. It looks a little involved. 1.) Allocate and associate an IPv6 block to the VPC. 2.) Configure internet gateway and routes in the VPC. 3.) Update security groups to include IPv6 in the VPC. 4.) Confirm current instance types support IPv6. 5.) Assign IPv6 address to instances. 6.) May require manual network setup on each instance if not using DHCPv6. This complexity (lack of abstraction) is why I prefer Google Cloud Platform. While GCP currently does not support IPv6, when they do support it, I am willing to bet they will roll it out as a turn-key button click.
- Slippery_John 10y agoI don't think your steps would be all that simpler on GCP unless you're running off app engine.
- hueving 10y agoI certainly hope that a click of a button doesn't log into my instance, adjust network configuration files, reload the network stack, and permit all ipv6 traffic in...
- nodesocket 10y agoEasy there.. I was not advocating any OS/instance level changes by Google. It is just that GCP seems to abstract away concepts like internet gateways and NAT instances, perhaps making the switch to IPv6 on GCP easier than AWS.
- borplk 10y agoCurious what practical benefits will an average site running on AWS get from IPv6?
- snuxoll 10y agoNot dealing with carrier grade NAT messing up your analytics from mobile carriers in the near future. T-Mobile and Verizon are pushing IPv6 hard because of address space depletion.
- masterleep 10y agoImproved connectivity to mobile due to avoiding triangular routing.

- tomschlick 10y agoBeing able to segment each of your services (mysql, web, etc) to a different IP as each machine should be getting a /56 or /64 at the very least.
- discodave 10y agoBut can't you do that with ports?
- tomschlick 10y agoyou can. but this can open up way more flexibility on how you run those services. think about something like docker where each app may be running web/db/queues/mail/etc. with v6 each docker app/service could have its own ip so you can run on the default ports. you could even create a subnet per app to segment them off easily.
- StreamBright 10y agoI am not sure this is a good example. I really like to have 1 IP / server, or maximum two when it has to live in two networks.
- subway 10y agoI really wish there were support for an IPv6-only VPC. Terminate inbound IPv4 at ELBs/CloudFront, use 464xlat or similar for outbound IPv4.
- bluejekyll 10y agoOut of curiousity, why? IPv6 is much more important on the edge, than inside your VPC. Is it just for the simplicity of your networking? One strategy is to define your IPv4 space inside one of your IPv6 networks such that you have dual addressing with directly mappable addresses. Do you have some other use case than just simplicity of design?
- dboreham 10y agoI'm not the OP but globally unique and optionally reachable from anywhere addresses are super-attractive from a not-going-insane perspective if you manage a non-triviality sized network.
- bluejekyll 10y agoAbsolutely, but the OP was talking about a 4-6 NAT, which seems less useful.
- subway 10y agoGP hit it on the head. Every node is globally addressable. Regarding the 464xlat, that's strictly to enable hosts in the internal network to communicate with external IPv4 only hosts. IPv6 is still used as the only internal transport, and primary external transport.
- bluejekyll 10y agoCool. That makes a lot more sense.
- cortesoft 10y ago
- brazzledazzle 10y agoHypothetically speaking, does anyone know if enabling IPv6 on a small VPC using 100% of its IPv4 addresses would allow you to spin up additional EC2 instances assigned IPv6 addresses?
- subway 10y agoDoubtful. All instances get an IPv4 address, which unlike IPv6 in AWS, is optional.
- thresh 10y agoFun fact: Ubuntu 16.04 image offered on Amazon does not support IPv6 out of the box. Even when you log in via ipv4, and make relevant networking changes (basically enabled DHCP for v6), it will still fail to apt-get update, because eu-central-1.ec2.archive.ubuntu.com is ipv4-only. Sad.
- thresh 10y agoAnd of course while it's Canonical's fault for not having a v6 dhcp, the similar problem affects Amazon Linux instances: repo.eu-central-1.amazonaws.com is ipv4-only so yum makecache fails.
- loganv 10y agoXenial's v6 dhcp has been working much better for me since this was fixed https://bugs.launchpad.net/ubuntu/+source/isc-dhcp/+bug/1633479 https://bugs.launchpad.net/ubuntu/+source/isc-dhcp/+bug/1633... Prior to that dhclient fix, dhcpv6 was basically unusuable on 16.04.
- OddBloke 10y agoOut of the box, an instance will come up with IPv4. If you then perform DHCP for IPv6, you should still be able to route to the per-region archive mirrors (which only serve over IPv4 because when they were deployed IPv6 wasn't available). If you disable IPv4 entirely, then it's true that you won't be able to access the archive mirrors. However, this isn't exactly "out of the box". :) If you do want to disable IPv4, then at the same time you'll also need to modify your /etc/apt/sources.list to point at archive.ubuntu.com (which does serve over IPv6). We're looking at how we can best make the "no IPv4" case work with the in-cloud mirrors, and hope to have that resolved soon.
- dustinkirkland 10y agoAfter a complex set of steps to setup ipv6 in my [VPC, Router, Gateway, Security Groups, and others that I'm forgetting], I was able to launch 2 instances and get both ipv4 and ipv6 addresses. As OddBloke notes, I did have to 'sudo dhclient -6' to grab that ipv6 address in the instance. Once I did, I was able to ssh back and forth using ipv6 (yay!). Then I tried 'apt update'. In fact, the mirrors inside of AWS worked us fine. But security.ubuntu.com did not. It did resolve, but it didn't respond. Rest assured we (Canonical) are working this right now... Thanks.
- hendry 10y agoSilly question, but doesn't ipv6 make mitigating DoS attacks all that more harder? i.e. you can't easily blacklist IP addresses...
