Reserved IIDs - TAKE 2

[Suresh Krishnan <[e-mail]>]

Hi Folks,
   Some RFCs (I know of at least 2, RFC2526 and RFC4291) reserve a set 
of interface identifiers on all prefixes. These identifiers need to be 
excluded when a node autoconfigures an address. This problem occurs with 
privacy addresses but is equally applicable to other address assigment 
methods like dhcpv6, cga etc. Instead of new documents referring to each 
of these RFCs individually it would be convenient to have a single store 
of information. Recently (due to upcoming RFC4941) I also found out that 
some of the documents reserving such identifiers may be on a lower 
maturity level than the ones that need to use the identifiers. Hence it 
makes sense to create an IANA registry for this purpose. I would like to 
hear people's opinions on this. I would like to pursue this either as a 
WG document or a personal submission. You can find my draft at

Thanks
