Hi,
| I understand that this is pretty much a bug in the *routers*, not in
| Ubuntu. The reason it's reported here on Launchpad and not in a thousand
| routers is because you're planning to implement a workaround in Ubuntu,
| right?
Yes (to both questions).
| What you are saying is, if I switch to another DNS server, then it *may
| not* be the same bug, but it *might* be (if my router is ignoring IPv6
| DNS requests, but the other DNS server is good). But it could be other
| problems with my router's DNS server besides IPv6.
If it works fine with Karmic and works fine with Lucid with IPv6
disabled, but is slow at resolving DNS with IPv6 enabled, that is this
bug. If it's slow with IPv6 disabled, that's really interesting as
well.
| But if I disable IPv6 entirely, and the bug does not go away, then it is
| not this bug. (I haven't been able to disable IPv6 yet).
In grub, add «ipv6.disable=1» after the line with loads the kernel (this
one presumably ends with «quiet splash»).
Can you include the output of running «ip a» in your reply as well?
Preferably both before and after disabling IPv6.
