[Sis-csi] IPv6?

[Marc Blanchet]

Hi,
  as you might have noticed, ARIN board recently advised the  
community that IPv4 addresses are going away and push the community  
to consider IPv6 asap... The concensus currently is that IPv4  
addresses will be gone by 2010 from the IANA pool and then x months  
later from the RIR pool.  Given that space projects are "long term"  
projects, at the time some IP address space will be needed for space  
in, say 2012, then v4 addresses won't be available. only IPv6  
addresses will be available.
  given the multi-international scope of space projects, I can't  
imagine having IPv4 NATs between spacecrafts that forces VoIP traffic  
to go through earth just because of traversing NAT... ouach....
  therefore, I think this group should really consider:
- ipv6 as the primary IP protocol
- ipv6 as possible only IP protocol
- designing a contingency plan if v4 is still considered.

comments?
