Yes, it is indeed possible to have Linux behave exactly like Windows
when you say "server assigned IP address". In every Linux dialup tool I
have seen it is the default, as it is in Windows, because it is correct
in 90% of cases. You do not give pppd a local address, so it gets one
from the server. The only cases I have seen where it was not correct
were PPP servers on private networks, not ISPs, where the normal cause
is the PPP server's being incorrectly configured. Such gross
configuration errors are uncommon with ISPs, as they go out of business
if their customers cannot connect.

As I pointed out, if you use Demon and request a dynamic IP address, you
will get one. It will be the same every time, because part of the Demon
service is to give you a fixed IP address.

I think we are failing to get at your actual problem. Why do you want
your IP address to change? I can see no possible benefit.

Regards, Ian

PS if Demon tech support really told you this I think someone needs a
little instruction in how their service operates.
