[IPv6]Re: Reclaiming fec0::/10 (I-D Action: draft-templin-6man-mla-01.txt)

[Bob Hinden <[e-mail]>]

Fred,

Proposing a new type of scoped IPv6 addresses is fine.   IMHO, there would need to be a lot of justification to warrant that in order to build a consensus in 6MAN and the IETF.

It is extremely premature to discuss what prefix to use for it at this point.

Bob 

p.s. I note your draft has no references to any other MANET work, nor any mention of a new addressing scope.
