Seems like it should be contained somewhere in /proc, but I'm unable to
locate it there in a reliable way.  I can see it in reverse hex in some
of the tables, but not in anything that authoritatively lists the IP
addresses on a machine.

I looked through the output of 'strace ifconifg'  to see where ifconfig
is getting it from, and it looks like it may come from
/proc/net/if_inet6 or /proc/net/dev  or possibly /proc/net/unix.
