You don't want to get rid of the 192.168.0.0 line, that tells you which
network is on the interface.
169.254 is, i believe, zeroconf. You can ignore it in any case.

Well, IP layer first - can you ping 82.133.85.65 from the command line?
(that's jolt.co.uk by the way).
If yes, then the route is working. Next, check you have the right
nameservers listed in /etc/resolv.conf. If you're on NTL then you'll
want 194.168.4.100 and 194.168.8.100. If you are behind a
router/firewall device sometimes you can use that IP address instead.

If that's set up right, check the nscd service and configuration, that
might be killing lookups.

If that fails, please post ifconfig -a and netstat -rn, and let us know
a bit more about your setup.
