I think SIIT communication using v4-mapped addresses should be represented as InetAddressType ipv6(2), and InetAddress of ::ffff:x.y.z.q .

I think that some implementations provide the zone concept for IPv4 communication, but no sin_scope_id in the sockaddr_in; thus the way to provide zone info is to use AF_INET6 sockets and IPv4-mapped addresses to communicate via IPv4 on the wire. However, since the address family in the MIB is supposed to reflect the address family on the wire, ipv4z is required to represent the zone info when performing this trick. (The zone concept is useful in v4 in some of the same ways as in v6, e.g. two different zones both using 10.0.1/24) Bill -------------------------------------------------------------------- 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] --------------------------------------------------------------------
