	<longdesc lang="en">
	This Linux-specific resource manages IP alias IP addresses.
	It can add an IP alias, or remove one.
	In addition, it can implement Cluster Alias IP functionality
	if invoked as a clone resource.

	If used as a clone, "shared address with a trivial, stateless
	(autonomous) load-balancing/mutual exclusion on ingress" mode gets
	applied (as opposed to "assume resource uniqueness" mode otherwise).
	For that, Linux firewall (kernel and userspace) is assumed, and since
	recent distributions are ambivalent in plain "iptables" command to
	particular back-end resolution, "iptables-legacy" (when present) gets
	prioritized so as to avoid incompatibilities (note that respective
	ipt_CLUSTERIP firewall extension in use here is, at the same time,
	marked deprecated, yet said "legacy" layer can make it workable,
	literally, to this day) with "netfilter" one (as in "iptables-nft").
	In that case, you should explicitly set clone-node-max >= 2,
	and/or clone-max < number of nodes. In case of node failure,
	clone instances need to be re-allocated on surviving nodes.
	This would not be possible if there is already an instance
	on those nodes, and clone-node-max=1 (which is the default).

	When the specified IP address gets assigned to a respective interface, the
	resource agent sends unsolicited ARP (Address Resolution Protocol, IPv4) or NA
	(Neighbor Advertisement, IPv6) packets to inform neighboring machines about the
	change. This functionality is controlled for both IPv4 and IPv6 by shared
	'arp_*' parameters.
