Yes. It is called IP aliases. If the addresses are on the same subnet as 
the first IP address assigned the easiest way is to give something like:

ifconfig de0 inet 192.116.93.18 netmask 255.255.255.255 alias

Note that you should use a netmask of all 1-s. If you want the new alias 
on a different subnet than the original you'll have to give the true 
netmask and also modify the routing tables accordingly. Look at the 
manual pages for ifconfig(8) and route(8), if necessary.
