[Sis-csi] IPv6?

[Schneider, Larry]

CEV has a requirement to support IPv4 with a transition to IPv6 for
lunar. By going early they avoid the cost to support both solutions and
an awkward program transition. 
 
Mobile IP is included and standardized in IPv6 whereas in IPv4 it is
supported only under proprietary solutions.
 
IPv6 eliminates private addresses.
 
I'm not suggesting it can't work either way, I'm only indicating how it
currently from my vantage.

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.
