I was having problems with ipv6 recently which is built into my kernel, but there's no way to disable it effectively as far as I know apart from recompiling it as a module which I wasn't in the mood for. Basically it was slowing down internet browsing a lot. I use firefox and it was sometimes taking 10 - 20 seconds to load a page. anyway, not much was working until someone suggested adding a nameserver entry to /etc/resolv.conf:

nameserver 4.2.2.2

Well, it works a treat, but i don't know why. Does anyone know?
Cheers!

[EDIT] Sorry, I meant to put this in networking.

4.2.2.1/2/3 are level3.com DNS servers. Which means they are very fast, but not primary DNS servers.

That sounds like a commercial network to me. Does my ISP pay for my access to that, or is it just that noone is noticing that I am using it? It's lightning fast though and I'm very pleased with it.

If DNS is on the internet, it is free. The internet is built on sharing. DNS is core to that, so yes you can use it.

ok, that's fantastic, long may it last.
cheers!
