That fully qualified domain name ("FQDN," the entire host and domain
names) was resolved by them doing a reverse lookup on your public
numerical IP address.  The whole thing, including the domain name
(pacbell.net) suffix was set by your ISP, that'll happen regardless of
what's set in your files that we've been talking about.

The ppp-71 will be related to the ISP's equipment that you've connected
up to.  Which could be PPP server 71, or the 71st port on it...

The xxx bits would be related to your connection.  Commonly they're
based on your MAC address, or your public IP address.  But since they're
created by the ISP, it could be anything, even randomly made up.

If your parameters are set up by DHCP, I'd expect all of that to be set
up when you connect to the ISP, but their server.  You probably don't
need to set any domain= parameter, yourself.  I've never set mine up to
match the ISP's.
