Yeah, I typo'ed there.  My bad.  I'm actually surprised your the first
to catch it (or call me on the carpet for it).

1) bring the up on IPv6.

2) Stick the address in DNS.

host www.ip6.wittsend.com
2001:4830:3000:2:204:8ff:fe00:1151

Do you really think I assigned that damn thing?  The MAC address is not
going to change.  That address has been assigned going on over a half a
decade (and the EUI hasn't changed in over decade through 3 provider
changes).
