Can you tell why I have all the time restart networking to get internet working? It comes and goes? (Hardy Heron, Xubuntu).

There could be lots of different reasons; please provide some more information so we can make a better assessment. Information like this would be useful:

-does networking crash at fixed intervals or does it seem random?
-does it crash when the machine is idle or only when you're using the Internet?
-do you notice it crashing only when you visit certain websites?
-you mention DNS in the title so I'm wondering why you think it's DNS...do you sometimes have issues resolving domain names?
-when networking seems to break, have you tried connecting directly to an IP address (i.e. avoiding DNS) to see if that still works? should bring you to google.com for instance.
-can you ping when the network crashes?
-what is the output of dmesg right after the connection crashes?
-what hardware and drivers are you using? If you don't know, please post the output of the command "lshw -C Network"
-how are you restarting networking (/etc/init.d/network restart or something else)?

When you get a chance, please provide this information so that you can be helped better.
