No, for the problem you described, *configuring* the DHCP client
through its configuration file is the way to go.

So the solution must be not to comment it out, but to change the variable value "DHCP" to something else. I've been searching for proper values but haven't seen them anywhere yet, but I did see the following in "man rc.conf":

You can statically configure the interface if you know the IP
parameters, and they won't change. However, I don't think that is
advisable in your case. Just keep your own DNS server by configuring
DHCP to prefer it to the DHCP-provided ones, and you're all set.
