MirrorManager 1.3.0 is live now. You can enter host names (A or AAAA records only please; it won't chase down CNAMEs) into your Host's netblock list, and MirrorManager will honor it. This means, if you have dynamic DNS keeping your A records up-to-date, MM will point your users at your mirror. As MM only does DNS lookups every hour, there may be a small window where your IP changes, DNS changes, but MM hasn't caught up yet.
Also, MirrorManager is now IPv6 enabled. mirrors.fedoraproject.org and download.fedoraproject.org are both reachable by IPv6, and it does IPv6 (and 6to4) GeoIP lookups too. The IPv6 GeoIP table is pretty limited, but with the addition of 6to4 lookups, I think will be quite usable. You can add your IPv6 netblocks too.
Thanks, Matt
