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?
Apache does support IPv6, though; some other content
which is served
using Apache, like lists.wm.o, is available over IPv6.
MediaWiki itself supports IPv6 fine, including for blocking. This was
implemented a while ago. Training admins to handle IPv6 IPs could be
interesting.
I mused on NANOG yesterday as to what was going to happen when network
techs started realizing they couldn't carry around a bunch of IPs in
their heads anymore...
(APNIC runs out of IPv4 space to give to providers
somewhere around
August, statistically; RIPE in Feb or March 2012, ARIN in July
2012).
ARIN issued the last 5 available /8s to RIRs *today*; we've been
talking about it all day on NANOG.
Not exactly. IANA issued the last 5 /8s to RIRs, of which ARIN is one,
today. But George is talking about RIR exhaustion, which is still some
months away.
His phrasing seemed a bit.. insufficiently clear, to me. That was me,
attempting to clarify.
Out of curiosity, is anyone from the Foundation on the
NANOG
mailing
lists?
Oh yeah; that's what triggered this. :-)
Does any useful discussion still take place on that list?
Sure. The S/N is still lower than the Hats would prefer, but that's
the nature of an expanding universe.
