I would suggest using dhclient as your dhcp client program -- it is
trivial to set up, and the config file is very straightforward. As far
as I can tell, dhclient is the preferred client program to use if you
have only one NIC being configured by dhcp -- which should be suitable
for the vast majority of users (so it is a mystery to me why the default
SuSE installation uses dhcpcd instead). The default dhclient
configuration in SuSE is to request (and require) a DNS update with each
dhcp request. I've used dhclient "out of the box" since getting my
high-speed connection, and have not had to change one line of the config
file.

If your service provider does not honour a DNS update request in dhcp
queries (you will have to check with them, of course), then you will
have to enter them manually in your /etc/resolv.conf file, and configure
your system not to update that file.
