Just a status update about ipv6 for msync.centos.org As of today, we now have 30 nodes (out of 69) having ipv6 connectivity on the nodes behind msync.centos.org Instead of just advertising the AAAA record for msync I'd like to implement it through a specific record (maybe like msync-v6.centos.org)
The reason is that if you have ipv6 and that we don't have your ipv6 address in the whitelist, I'm afraid that rsync will try over ipv6 directly, and so would be blocked as long as we don't have the proper ACL in place for ipv6 mirrors
So the idea would be to have something like msync-v6.centos.org::CentOS-v6, and ask you to provide us the ipv6 address for your mirror (we can already do that in advance if you advertise AAAA record on your side for your mirror) and so it would be an "opt-in" thing (at least as a start)
Then, we can decide to merge the ACLs and also have AAAA record for msync , after enough people will have confirmed that everything works.
Ideas, comments, suggestions ?
I think this is a reasonable way to do that, hence rsync provides a "-4/-6" option to let you choose which internet protocol to prefer.
IMHO it is safer to have a separate v6 DNS. But this is only because there is access authorization done on IP level, in other cases I would strongly encourage to have A and AAAA records for the same name.
"msync-v6.centos.org::CentOS" sounds more semtantic to me.
