Dial-up? That sounds like the point-to-point protocol daemon (pppd).
Traditionally, it is started by "pon" and stopped by "poff". There are
configuration settings for ppp which control this. Here's a link to
some information about configuring ppp:
http://www.wowway.com/~zlinuxman/tp600.htm#Config.
This is in the overall context of my "Linux on ThinkPad 600" webpage,
and it does not address your specific concern, but it does provide
some basic information on configuring ppp. In particular, /etc/ppp/peers/provider
looks like the file you need to edit. The "usepeerdns" option is
apparently what you *don't* want. As to the domain name and IP address,
that's pretty much up to your ISP. They control their own domain name,
and they assign you an IP address. They probably control your hostname too,
as seen by outsiders.
But you *can* supply your own DNS servers if you want. You just have to make
sure that you're not using the "usepeerdns" option.
