Dynamic IP and DNS

[Marcus]

I'm trying to help somebody else connect to the network at his office. 
According to the administrator it uses dynamic IPs and DNS. How do they 
set this up?

I cannot actually check it out myself, just try to explain it to them in 
simple terms. Basically, I guess they go into kcontrol and setup the 
network card, but since there is no static IP or DNS, what do they enter?

Thanks,

Marcus
