	as I wrote, if you want to use specific interface id (lower 64 bits)
	you can swap link-local address.  I don't recommend it since
	we did not make extensive tests for it.

	If you want the following:
	- For servers
	- put name-address mapping onto DNS
	- and would like to use the mapping across ethernet card replacement
	it is covered.

	You should be okay if you configure extra address.
	# ifconfig ne2 inet6 3ffe:501:ffff::1 prefixlen 64 alias
	and put it onto DNS.	IN AAAA	3ffe:501:ffff::1
	You do not need to worry about extra addresses configured from
	MAC-address based link-locals.  If you don't advertisem them in
	DNS, they won't be used by clients.  When you initiate a connection
	from the server, it may occasionally be used.
