Anyone know what's the biggest hold up of IPv6 on AWS side? They must be working on this for years, but never heard of any push or beta program at all.

AWS does support ipv6 in ELBs in a fashion. ELBs will have both an ipv6 and a dual stack DNS entry created for them, in addition to the ipv4. example.us-east-1.elb.amazonaws.com (A Record) ipv6.example.us-east-1.elb.amazonaws.com (AAAA Record) dualstack.example.us-east-1.elb.amazonaws.com (A or AAAA Record) These records will only be displayed for ELBs in classic despite existing and being resolvable for VPC ELBs. Th…

Thanks did not ipv6 version exists. Now you are bringing the right thing... IPv6 support in VPC SG.

Well, public services are not. ELB for example. If AWS continues to grow, I think they will eventually exhaust their IPv4 blocks and this is an issue they can't ignore.

ELBs in EC2 Classic support IPv6, but not ELBs in VPCs, as of now at least. You may already have known this but I figured I'd point it out for others: http://docs.aws.amazon.com/ElasticLoadBalancing/latest/Devel...

I wasn't even aware of IPv6 support for Classic. Thanks.

Easy, the same way HDTV over the air was accomplished. There will be a legislated rule that ipv4 will be outdated, and the tech brokerse will need to deal with that over a decade.

Apple has started to require IPv6 support for app store approval. I see this as an interesting approach that could push adoption, at least on the backend side.

> AWS & GCE that's because they have plenty of v4 space, which is now a competitive advantage. have you tried to get even a /24 lately? pay up, sucker. bitspace is now a market with exponential returns. it's the ultimate barrier to entry. the faster they move on it, the less of a barrier it will be to the competition. so why should they? welcome to the new microsoft. except this time, we're all eating it up and lovin…

They don't really... I've heard the internal addressing at some cloud providers is a real mess. Multi-layer NAT, etc.

Amazon has a significant push to VPC, so then instances will all be on e.g. 10. Address space (so they're doing NAT).

To me it looked like this: - I've got a new modem from aaisp.net and didn't have to do anything. - I've checked an "IPV6 (BETA!)" checkbox in my hosting provider's control panel. - I've copied & pasted my new IP and added it to AAAA records for my domains. And to my surprise, everything just worked. My mobile phone used IPv6 even before I knew. I didn't have to troubleshoot anything. The biggest snag I ran into is th…

People who can choose between Comcast and Comcast are laugh-crying right now

Not sure I get that statement. I've got comcast and I've had a /68 for quite awhile. Works great. From what I can tell comcast pushing more IPv6 than most.

Linode supports IPv6: [prhodes@doctorfeelgood ~]$ ping6 -n www.fogbeam.com PING www.fogbeam.com(2600:3c02::f03c:91ff:fe84:7b1d) 56 data bytes 64 bytes from 2600:3c02::f03c:91ff:fe84:7b1d: icmp_seq=1 ttl=55 time=31.7 ms 64 bytes from 2600:3c02::f03c:91ff:fe84:7b1d: icmp_seq=2 ttl=55 time=39.8 ms 64 bytes from 2600:3c02::f03c:91ff:fe84:7b1d: icmp_seq=3 ttl=55 time=38.6 ms ^C

Thanks! Just looking at this makes me feel for network operators that have to troubleshoot layer 3 addresses directly and without DNS. There needs to be a better approach - like an intelligent clipboard.

I'm far from an expert on ipv6, but I think there may be some "shortcuts" that let you work with less than the full address. See, for example:

.. or they haven't .. VPC gives you your own entire rfc1918 space per region, which tho can be a pain to deal with overlap if you have site-to-site VPN, is enough for basically anyone.

You can avoid RFC1918 overlapping issues by using some overlay networking solution like Wormhole[1], which uses the CGNAT reserved IP space to build a virtual network between your servers, regardless of their location.

This pain point is one of the reasons we've built Wormhole.
