In that case, you are not using static IPs. If your ISP has assigned you 
- as in Poly's example - 123.456.789.1 through 123.456.789.25, then 
those addresses are for your use to assign as you see fit. You would 
configure this machine's interface for any address in that block. You 
can then configure the same interface for more than one of those, or use 
your extra IPs for other machines (or interfaces). Instead of 
ifconfig_xl0="DHCP" in rc.conf, you might have 
ifconfig_xl0="123.456.789.16 255.255.255.128" or some such.

HTH.
