RE: Using IPv6 with prefixes shorter than a /64 on a LAN

Even if every RIR gets to 3 /12s in 50 years, that's still only 15/512ths of the initial /3 delegated to unicast space by IETF. There are 6+ more /3s remaining in the IETF pool.

That's good news - we need to make sure we have a /3 for both the Moon and Mars colonies. ;) Nathan
