I've recently had a strange dns problem with my new netcom adsl router.
Windows client worked fine with it.  Ubuntu didn't.  I changed
my /etc/resolv.conf to point to the isp's nameservers, rather than the
adsl router and all the problems went away.  If I did an nslookup on the
adsl router, it would sometimes return 10.0.0.1 as the address, which
was of course the routers own address.  I haven't investigated any
further to find out why.
