From my neighborhood Sun server:

	# ifconfig -a
	le0: flags=63<UP,BROADCAST,NOTRAILERS,RUNNING>
 	       inet 139.93.30.1 netmask ffffff80 broadcast 139.93.30.0
  --->         ether 8:0:20:7:aa:77 
	ie1: flags=63<UP,BROADCAST,NOTRAILERS,RUNNING>
	        inet 139.93.1.8 netmask ffffff80 broadcast 139.93.1.0
