Re: draft-bourbaki-6man-classless-ipv6-00

Hi,

The flexibility of IID length will bring some benefits.
But, is there any compatible issues to concern?

For example, if two networks are assigned with two length IID in office and 
at home,
the host, such as mobile phone, pad or note PC must adapt to the different 
IID lengths.

Is it practical or available nowadays to have such adaptabilities.
Is it a required to have a default IID length, eg. /64 for the local link?
Should the default length be supported?

I should add,

The IID length used by all SLAAC hosts on a link would be the same, because 
presumably, they all receive the same RAs. With the same RAs, their IIDs 
would have to come out to be the same length.

And, most of this change doesn't even apply to RFC 4862. For the most part, 
it applies to RFC 2464-bis. The main points of RFC 4862 remain the same.
