Hi - I gave this draft a quick review in preparation for identifying what we might discuss in our next meeting in Dallas.
It is unclear to me what the relationship is between draft-song-sunset4 and draft-davey-sunset4, and I think they should probably be integrated into one draft. Or does the newer draft supersede the other? If the one supersedes the other, I can send mail to the secretariat so that the metadata reflects that. Either way, there are additional things to discuss in this space, such as the interaction between the DNS server, IPv4 transition/life extension technologies, address selection, and happy eyeballs. Some of it is covered in draft-ietf-dhc-conn-status-00, but I'm not certain what the status of that draft is. The problem statement we discussed at a DHC/Sunset4 joint meeting was as follows: •Many networks will have both IPv4 and IPv6, but with varying transition technologies affecting the quality of those stacks –“real” IPv4 (no CGN) –CGN IPv4 (potentially broken for some apps) –NAT64/DNS64 (also potentially breaks things) –IPv6 (only) •How do you tell dual-stack hosts which to use/avoid? –For which destinations? –With which protocol(s)? –Happy Eyeballs helps, but can be non-deterministic Thanks, Wes From: Davey Song <[email protected]<mailto:[email protected]>> Date: Monday, October 27, 2014 at 9:00 PM To: "[email protected]<mailto:[email protected]>" <[email protected]<mailto:[email protected]>> Subject: [sunset4] Fwd: New Version Notification for draft-song-sunset4-ipv6only-dns-00.txt Hi folks, I have just post a new draft on IPv6-only DNS development. Comments are welcome!! A new version of I-D, draft-song-sunset4-ipv6only-dns-00.txt has been successfully submitted by Linjian Song and posted to the IETF repository. Name: draft-song-sunset4-ipv6only-dns Revision: 00 Title: Considerations on IPv6-only DNS Development Document date: 2014-10-27 Group: Individual Submission Pages: 8 URL: http://www.ietf.org/internet-drafts/draft-song-sunset4-ipv6only-dns-00.txt Status: https://datatracker.ietf.org/doc/draft-song-sunset4-ipv6only-dns/ Htmlized: http://tools.ietf.org/html/draft-song-sunset4-ipv6only-dns-00 Abstract: Deployment of IPv6-only networks are impacted by assumptions of IPv4-only or dual-stack transition scenarios. For example, these assumptions are in the operations of DNS. This memo is problem statement and hopes to eventually propose a mitigation technique. Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org<http://tools.ietf.org>.
