And after 75 messages, nobody has asked the obvious question. When is 
ARDC going to acquire IPv6 resources on our behalf? Instead being all 
worried about legacy resources we're highly underutilizing.

Ham Radio is supposed to be about pushing the art forward. Let's do that.

The reasons for that are two: (1) IPv4 isn't forward compatible with anything (if it had a TLV or equivalent for the address, we could have simply extended the address), and (2) 2^32 is a finite number less than the number of addressable entities in the world. Yes, it would be interesting to use Class E as unicast space. The instant we make it possible, it will be bought up by companies and countries desperate to delay their IPv6 deployment - and we will then, once again, be out of IPv4 space.
