From: "George Herbert" george.herbert@gmail.com I have to admit to having been negligent in examining the IPv6 readiness of the Mediawiki software. Is it generally working and ready to go on IPv6?
Is Apache? That's the base question, is it not?
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.
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.
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.
(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.
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?
