Re: Portability of 206 address space

The interNIC has already stated that allocations can *not* be guaranteed
to be 'routable', so it stands to reason that the interNIC (or any other
registry, for that matter) need not concern itself with the issue of
portability. As you mentioned, this is strictly a matter between the ISP(s)
and the customer(s).

      Please clarify "portable" as used in this context.

      - Routable between different providers
      - Transferable intoto between ISPs
      - Transferable subsets
      - Some other meaning

      No delegation registry can claim any prefix portability if 
      the first option is the meaning. The second has applicability
      to various proposals for a prefix market once a delegation
      has been made. (no Internic involvment)  The third is strictly
      between ISPs and thier clients and has a lot to do with 
      prefix migration (nee punching holes in CIDR blocks) and nothing
      to do with the Internic.  And then there is your possible
      other meaning...

      For the first three, the Internic has zero sane reason for
      issuing any "edict" wrt portability. That is strictly an
      ISP issue.  The fourth... ??? :)
