Comment 121 for bug 417757

Ah, Tollef shed some light on this. Ubuntu's glibc up to early Karmic had a patch applied which disabled unnecessary IPv6 DNS lookups (http://err.no/patches/glibc-only-lookup-ipv6-if-it-makes-sense.diff). This was dropped in Karmic to fix some IPv6 lookup issues (bug 239701, bug 374674), but also caused this regressions.

Mithrandir| so I suspect somebody should take my patch, refine it so it doesn't just reject v6 addresses (try again after processing if there no hits, allowing ipv6 then, or something like that)

I confirm that in my dapper to jaunty chroots "normal" applications like wget, apt-get, firefox etc. work just fine. I was just misled to think it'd be a kernel issue because I used "host" (which also times out).

http://bugs.debian.org/435646 is related to this, BTW.
