The author of that page assumes that every machine is always running a
nameserver. This is, of course, not true.

Run pppconfig and configure a connection for each ISP, specifying the
correct nameservers for each ISP (or 'dynamic' if the ISP uses so-called
'dynamic dns'). Everything will just work.

A nameserver. But you don't need or want to do that.
