I created a script, that can be accessed outside of the zone (copied in, NAS
mount, etc - but doesn't require any special build/access for the zone).
It looks for a common MAC from the zone's MAC to the global zone's MAC. It
isn't perfect, but gives a list of IPs to look against.
#!/bin/ksh

#
# Tries to determine the global name for the local/non-global zone by using arp.
# May not always be accurate or successful.
