It doesn't matter if Apache supports IPv6, since the Internet-facing HTTP servers for wikis are reverse proxies, either Squid or Varnish. I believe the version of Squid that WMF is using doesn't support IPv6.
Oh, of course.
As long as the proxy supports IPv6, it can continue to talk to Apache via IPv4; since WMF's internal network uses RFC1918 addresses, it won't be affected by IPv4 exhaustion.
It might; how would a 6to4NAT affect blocking?
It's not really a 6to4 NAT per se - it's a 6to4 application level proxy. The question is, what does Squid hand off to Apache via a IPv4 back end connection if the front end connection is IPv6.
Which, frankly, I have no idea (and am off investigating...).
