Ooops... :-} I guess I read some older RFC first, and the change never registered on reading updates (and after implementing the first version). I have all the time falsely assumed that IPv6 address for a specific link layer was n-bit prefix and 128-n bit identifier, where n could be almost anything between 0 and 64. So, there is only those addresses starting with 000 where anything is possible. Thats lots of addresses still, so maybe I keep the implementation as it is :-) -------------------------------------------------------------------- IETF IPng Working Group Mailing List IPng Home Page: http://playground.sun.com/ipng FTP archive: ftp://playground.sun.com/pub/ipng Direct all administrative requests to [EMAIL PROTECTED] --------------------------------------------------------------------
