We are planning on implementing an SNMP MIB table that represents packet trace parameters per interface. One of the parameters users can specify is the IP address so that we will only trace packets whose source/destination IP address match a user specified IP address value. Due to the fact that SIIT supports IPv4-mapped IPv6 IP addresses on the wire, we permit users to trace packets with IPv4-mapped IPv6 addresses for an IPv6 interface. How should an IPv4-mapped IPv6 address be represented using the SNMP textual conventions from RFC3291? Should the InetAddressType MIB object be set to unknown(0) or ipv6(2)? Should the InetAddress MIB object contain a 16-octet IPv4-mapped IPv6 address?
Also, we are confused about the following explanation in RFC3291:
- The InetAddressIPv4z is intended for use in MIBs (like the TCP-MIB) which report addresses in the address family used on the wire, but where the entity instrumented obtains such addresses from applications or administrators in a form which includes a zone index,
such as v4-mapped IPv6 addresses.
