#!/Perl
#   GetIP.pl
#   --------
#   This will retrieve all IP Addresses that are bound
#   to network devices on a specified machine. This includes IPs that are
#   bound to any NIC (network card, RAS dail up, etc).
#   If a particular NIC specifies 0.0.0.0 (typically to indicate that the
#   NIC will request an IP via DHCP, PPP, etc) it will be ignored.
#   ALL IPs are discovered even on cards that are disabled.
#
#   Syntax:
#       perl GetIP.pl [Machine Name]
#
#   Examples:
#       perl GetIP.pl
#       perl GetIP.pl \\server
