Hello, I have a question about the procedure to follow in order to request the allocation of a special multicast address and a protocol message type number. We've already contacted IANA (at [EMAIL PROTECTED]) and ICANN (at [EMAIL PROTECTED]), but we haven't received any answer yet. We are working on the specification of the MLDv2 protocol draft, the IPv6 version of IGMPv3. (http://www.ietf.org/internet-drafts/draft-vida-mld-v2-00.txt) In the specification of the protocol we need the followings: 1. the allocation of a special IPv6 multicast address called "all mldv2-capable routers". For IGMPv3 IANA already allocated the IPv4 multicast address 224.0.0.22 for "all igmpv3-capable routers". As normally there is a correspondence between specially assigned IPv4 and IPv6 addresses, we think FF02::16 is the suitable address for all-mldv2-routers. But the only document that we found listing already assigned IPv6 multicast addresses is RFC2375, dated July 1998. So we are not sure that this proposed address is not already allocated. For IPv4 there's a much more recent document available at (http://www.isi.edu/in-notes/iana/assignments/multicast-addresses - March 2001) 2. the allocation of an ICMPv6 message type for MLDv2 Report messages. In the first version of the draft we mistakenly considered the value of 136 for this message type, but this value is already allocated to Neighbor Advertisment messages. As far as we know, the first available message type value is 143 (141 and 142 are experimental assignments for mtrace messages). But before releasing a new, corrected version of the draft, we would like to officially request the assignment of this value (143) for MLDv2 reports. We would appreciate if you could give us a hint on how to proceed in order to do these allocations. Maybe you've already faced a similar situation. Or can we just release the new version of the draft, with the considered values, and hope that IANA will confirm our assignments? Thanks in advance, Best regards, Rolland Vida Luis Costa -- ______________________________________________________ Make everything as simple as possible, but not simpler - Albert Einstein Rolland VIDA - Ph.D. student Universite Pierre et Marie Curie Laboratoire LIP6-CNRS, 8, rue du Capitaine Scott Tel: +33 (0) 1 44 27 71 26 Fax: +33 (0) 1 44 27 74 95 E-mail: [EMAIL PROTECTED] Web: http://www-rp.lip6.fr/~vida ______________________________________________________ -------------------------------------------------------------------- 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] --------------------------------------------------------------------
