I find it interesting that this didn't make into the keynote. Is the actual interest really low?

Most 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).

The opposite pattern is much more convenient: IPv4 on the public endpoint and IPv6-only internally. AWS is now close to supporting this. http://blog.ipspace.net/2014/03/facebook-is-close-to-having-...

8 IPs per instance, max :/

Might be a dumb question, but why would you want or need more than one IP address for an instance? It's not like more addresses will let you download/upload things faster. Maybe if you want to run multiple web servers on port 80 and give each one a different IP address, but how often do people do that, especially more than 8 times over?

Containers. IP per container.

Finally! It's been a major deficiency in AWS. Can't wait to see this roll out to us-west-2.

I'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.

Just curious but why is IPv6 support such a priority for you that it would be the deciding factor in your choice of hosting provider?

In 2017, one should instead ask why it wouldn't be.

s/AWS/everywhere but Google/

Google's public services are fully dual-stack, but Compute Engine doesn't support IPv6 at all.

I think "about damn time", but I definitely want these posts - I use AWS despite its flaws, and it's important to me to know what's going on.

As long as AWS is both widely used by existing users, and is a likely option for new users evaluating alternatives, these AWS posts are always relevant on HN.

Pardon 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?

Most 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.
