Resolving http addresses

[Clayton Stapleton]

I have a problem when I enter a URL (http://www.google.com/) or others
my system does not resolve the address. I have looked at
/var/log/messages and it shows that the pppd connection is made
with the IP and DNS addresses show. This work before I reinstalled
Debian but now it just hangs. Any help will be appreciated.
TIA
