Hi Eric,

sounds like it's worth a discussion for a feature request. Could you please open a github issue? The only tricky
thing which comes to my mind right now is how to handle multiple matches for the ip address.

In the past I had SNMPTT configured to send traps to Nagios using the "$ar" variable, which passes the IP address of the SNMP agent sending the trap. Nagios happily accepted the IP address as argument 0 for the submit_check_result. It seems like Naemon will really only accept the host_name of the device, otherwise I am prompted with the message:

Frankly I figured using the IP address would be more secure and unique than using the short hostname (but I will admit, IP addresses aren't required to be unique in the config but host_names are). Even if I populate all my devices into an /etc/hosts file (which I really would prefer not to do) some devices that send traps do so by relaying through another device, so the "$ar" variable was the only way to distinguish the actual agent. Trying to use the SNMPTT "$A" hostname variable with any traps being relayed still results in just a plain IP address getting submitted to Naemon, which doesn't work.
