PPP does not require a dns server address to be provided.
But most folks do provide one because it would make for LOTS of support
calls to not hand out your DNS servers.

Is there a DNS on the network that your connecting to at all?
If not then you wll likely be forecd to use the /etc/hosts file to add
in the IP addresses of the target systems.
