I am not aware of a transport mapping for V1 SNMP over IPv6; IPX, OSI etc but not IPv6 so the agent SHOULD have a non-IPv6 address as well as an IPv6 one.
For non-IP (v4) protocols, I understand that the NetworkAddress in the Trap PDU should be set to
although a quick scan of the RFC does not tell me why I think so!
