Well, you *can* have the dhcp client on FreeBSD send an identifier, and
with that identifier the dhcp server can assign the client a static ip
lease. If that static ip is registered in your local dns, you're all
set. Doesn't work well if you use the client on another network who
doesn't offer static ip's. YMMV.

Isn't the proper way with dns to configure dynamic DNS updates, and
allow the client to do that?
