Because not all hosts have IPv4 address. Also, hosts may have multiple
IPv4 addresses. The inclusion of an IP address in v1 traps was quickly
realized to be a mistake.
The new strategy is to identify the SNMP engine that generated the
trap. This has lots of benefits, which I don't have time to elaborate. The
NMS is responsible for identifying the engines it is managing and keeping track
of their egineIDs, so when a v2 notification arrives, the NMS will know which
address or set of addresses (it is valid for an SNMP engine to manage multiple
addresses, or how would roiuters get managed?) it comes from.

In net-snmp, informs are already implemented for clients and master
agent.
