Doesn't the PPP server normally provide the DNS address?
https://www.rfc-editor.org/rfc/rfc1877.html#section-1.1

I'd have expected so, but that RFC says "By default, no primary DNS address is provided."

Can you reach hosts by IP address?
PPP does not work the same way as a LAN does. On a LAN, DNS would normally be provided by the DHCP server. However, since PPP links provide the IP address, no DHCP server is used. Also, I believe there's a slightly different DNS provided for Windows clients. How is that network set up? Perhaps for Windows clients and you're using Linux?
