	An IPaddr resource is an IP address which is to be taken over by \\
	the owning node.  An argument is required, and is of this form:
	    nnn.nnn.nnn.nnn/bbb.bbb.bbb.bbb
	Where nnn.nnn.nnn.nnn is the IP address to be taken over, and\\
	bbb.bbb.bbb.bbb is the broadcast address to be used with this address.

	Since IPaddr is the "default" resource type, it is not necessary\\
	to prefix the IP address by "IPaddr::".
	This allows IPaddr::192.2.4.63 to be abbreviated as 192.2.4.63.

# Revision 1.33  2002/12/10 22:18:39  horms
# If IPaddr is running on Linux, and a VIP is obtained that
# is on a loopback alias, then the loopback alias and the associated
# route if it exists, is removed before the alias, usually on an ethernet
# interface, is brought up.
#
# When the VIP is relinquished the alias on the loopback is restored.
#
# This is intended for use in conjunction with the LVS, where the
# same host may be a Linux Director and a Real Server.
#
# This feature explictly only works on Linux, as LVS only works on Linux.
#
# Thanks to Lorn Kay who did a lot of the ground work to get this fix working.

#
# Revision 1.25  2002/08/02 22:50:43  alan
# Put in a minor Solaris bug fix for IPaddr.
# If we get a MAC address that is missing a leading zero, then we add

#
# Revision 1.24  2002/08/02 03:29:16  horms
# Reworked Lorn Kay's loopback interface patch for Linux.
#
# Notes:
#
# This script assumes that an IP address can only belong
# to one interface. This is _wrong_. However, it works for
# almost all cases so I'm happy to leave it as is for now.
#
# In the mean time, this work arround allows us to have
# manages addresses on the loopback interface on Linux,
# which is very useful when heartbeat is used in conjunction
# with the Linux Virtual Server, and a node is both
# a Real Server and a Linux Director.
#
# Revision 1.23  2002/07/30 17:33:34  horms

# Lorn Kay's patch for IPaddr to better handle the presance of

# Designed for use in conjunction with LVS Direct Routing.
# Should be fully backwards compatible.
#
# Revision 1.21  2002/07/09 16:42:22  msoffen
# Deleted extra "debugging" lines .
#
# Revision 1.20  2002/05/28 18:25:48  msoffen

#
# Revision 1.19  2002/05/15 04:25:47  msoffen

#
# Revision 1.3  1999/11/16 04:36:53  alan
# Added fix from David Jules to make IPaddr work in France.
# The problem is that various commands that IPaddr invokes (notably ifconfig)
# produce different output in other locales than they do in LC_ALL=en
# so the output wasn't recognized by IPaddr.  The fix is much simpler than
# this explanation :-)
