	::<ipv4> is essentially dead

	::ffff:<ipv4> is used on IPv6 sockets to talk IPv4 or to
	        record IPv4 address along side IPv6 addresses.

	2002:<ipv4>:: (6to4) is not recommended.

	4in6 is a method of tunneling IPv4 packets inside IPv6
	packets.  It has the all the draw backs of tunneling packets.

	If you want to use IPv6 go request a /48 IPv6 address block
	and use that for your site.  You can run IPv4 and IPv6 in
	parallel.  This is called running dual stacked.

	If you can't get IPv6 enabled on your upstream link there
	are a number of IPv6 tunnel providers.
