This basically means you do not actually use DHCP for your
"client" machines (or better: for _your_ machines, be it
servers, desktop computers or firewalls); instead you have
to configure the components that would be DHCP's task on
a dynamic IP connection.

This is:

1. In /etc/rc.conf you need to configure the NIC(s) of your
   system to the IPs you want them to have:

	hostname="foo.example.com"
	ifconfig_xl0="inet 123.456.789.10  netmask 0xffffff00"
	ifconfig_xl1="inet 123.456.789.11  netmask 0xffffff00"
	defaultrouter="123.456.777.100"

   Maybe your ISP also defines a default router for you.



2. In /etc/resolv.conf, you have to define name servers if
   you need them (or you run your own one). Typically the
   ISP will tell you which NS _he_ offers.

	search example.com
	nameserver 123.456.700.100



3. You would also add entries to /etc/hosts reflecting your
   host's settings:

	123.456.789.10 foo.example.com foo
	123.456.789.11 foo.example.com foo


All this implies that those settings are quite static. But for
a static IP that might be fully desired. :-)
