Karabir suggested we start getting together a list of steps that need completion to deliver an IPv6-preferenced or IPv6-only list of mirrors for IPv6-only clients using CentOS. Here's what I've got so far. Feel free to add to it:
Steps are in order of priority:
- Establish at least two authoritative name servers for centos.org with v6 IPs. - Determine if centos.org registrar supports v6 glue, transfer to a registrar that supports it if needed, then add the glue. - Augment the current mirror database with a field for IPv6 support and IPv4 support, filling in IPv4 as enabled for all existing mirrors. - Build a list of centos mirrors which have AAAA records and/or consult with mirror admins to identify the mirrors which are prepared to provide preferred IPv6 connectivity to IPv6 clients. - Prepare a separate monitoring system for IPv6 content to confirm that mirrors are serving the content correctly over both v4 and v6. - Modify the mirror list on mirrorlist.centos.org to provide IPv6 mirrors with a higher priority than IPv4 mirrors when the client accesses it via its AAAA address rather than A. - Add AAAA for mirrorlist.centos.org
