# Plugin for Registry Ripper; Get information on network 
# interfaces from the System hive file - start with the
# Control\Network GUID subkeys...within the Connection key,
# look for MediaSubType == 2, and maintain a list of GUIDs.
# Then go over to the Services\Tcpip\Parameters\Interfaces 
# key and get the IP configurations for each of the interface
# GUIDs
# 
# Change history
