Here's an: "ifconfig -a" output from one of my AIX systems:
# ifconfig -a
en2:
flags=4e080863<UP,BROADCAST,NOTRAILERS,RUNNING,SIMPLEX,MULTICAST,GROUPRT,64
BIT,PSEG>
inet 168.162.21.50 netmask 0xfffffff0 broadcast 168.162.21.63
en4:

As you can see for each interface it has the netmask listed in what looks
to be hex, how do you convert this. What I have to do now is go into smit
and display the characteristics of each interface to get the netmasks
(ANNOUYING!!!). Does anyone know how "0xfffffff8" is: "255.255.255.248" on
en3? What method do I use to convert this so I can figure out the netmask
of any AIX interface just by looking at the "ifconfig -a" output. Any
assistance would be greatly appreciated thanks!.
