If you are getting you IP address through DHCP, this file gets updated
anytime DHCP gets a new address. The contents are comming from your ISP,
so tell them their servers are broken. If you want to specify a particular
nameserver and keep it there, you can try a few things. I generally do
this the "wrong way", but it works for me. I change the /etc/resolv.conf
to what I want, then I run (as root) 'chattr +i /etc/resolf.conf'. This
will make it so that even root can't directly change the file. (you would
need to 'chattr -i /etc/resolf.conf' first) If you have a firewall set up,
you can run named on your own box and tell /etc/resolv.conf to look at
127.0.0.1 and it will work fine.
What's the "right way" you ask? I was afraid you would ask. I forgot.
That's why I do it the "wrong way". But it involves the network scripts.
