Well, in such a case, I expect that traps be sent to both destination IP addresses. In other words, I expect traps be set to all addresses returned by getaddrinfo provided an appropriate source address is available.

We use net-snmp to send traps to user configured trap receivers. Until now, users could have configured only an IP address for trap receivers. Now, we have enhanced our system so that user can configure FQDN as well for trap receivers. We would like to feed user configured FQDN into net-snmp so that net-snmp can resolve the FQDN into an IP and determine the transport domain (UDP or UDP6) before sending the traps. 1. Is this possible in any of the net-snmp release versions? 2. If not, what workaround do you recommend? [ We currently, resolve FQDN into IP addresses and create trap sessions for each such resolved address. This works alright but has its own limitations. For example, DNS Server should be reachable when trap sessions are being created. Also if user decides to host trap receiver on a different server (same FQDN but different IP), then he will have to reconfigure the trap receiver on our device ] We use the following APIs to setup net-snmp for SNMP v1/v2c/v3 traps: 1. create_trap_session 2. snmpTargetAddrTable_create, snmpTargetAddrTable_add, snmpNotifyTable_create, snmpNotifyTable_add, snmpTargetParamTable_create, snmpTargetParamTable_add We currently use net-snmp-5.4.2.1-ssl-1.
