Just my $0.002: I had horrible DNS resolution times ( > 10 seconds ) for a long time and I assumed that it was because my router / ISP didn't support ipv6, so I went through the hassle of turning off ipv6 and the problems that come from that.
This week I decided to switch to openDNS http://en.wikipedia.org/wiki/OpenDNS and to my surprise I had no more DNS resolution problems! So unless you know for sure that your hardware or ISP does not support ipv6, try using another DNS service ( I recommend openDNS as it also has other benefits over traditional DNS services ). -- IPv6 should be disabled by default https://launchpad.net/bugs/24828 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
