Greetings
Moorse(sp) law is a great mitigator to address space cost in space.

At this point it appears likely that CEV and MS will support IPv6 from
the outset. An answer is expected in the summer timeframe.

I personally don't think address space is a driver in determining NASA's
space protocol needs. Space assets are very expensive and I doubt there
will be a significant number off addresses required. NASA already has a
significant allocation of v4 address it can use. Either version will
work from an address space point of view.
