I'm still having the same issue while trying to use any web browser, takes forever to resolve a name, have to reload every page twice until I get it.

I have ipv6 disable:

cat /proc/sys/net/ipv6/conf/all/disable_ipv6
1

Also Firefox have IPv6 Disabled.

But tcpdump still report IP6 stuff:

I don't know if they are related.
This happen with WiFi and Wired cable.

I don't know what else to do to post more info about this bug, and as some other are reported in this same bug we need some directions, in my opinion it isn't Fixed. I don't have this problem in debian, fedora and centos (the other 3 distros i use), it is only happening in Ubuntu 9.10 and 10.04 (Same Laptop, tested with all the other distros), 8.04, 8.10, 9.04 doesn't have this problem.
