>If this effort is only aiming at some niche within the universe of devices that could have (but hopefully won't have) permanent identifiers known to networking kit Quick response regarding the term permanent identifier: - This is not there in the charter - This is no more permanent than any identity used for any AUTH method today (IETF defined) - If this is used in any of the documents - this is to differentiate from the temporary nature of the anonymous identifiers (e.g: LISP anonymous EID). These can't be used for AUTH. - Though it's up to the community decide which AUTH method - there was a precedent for this term - one *example* RFC 4187/5448 - would be happy to replace with any other term which indicates the intent -- Uma C.
