Hi scott,

please check below screenshot.

The server that is actually offering DHCP requests on your network is from 152.63.2.94 not 172.27.27.104

If you are expecting one from 172.27.27.104 it is not being received from the Nagios server.

this wouldn't be an issue with the plugin, but the server actually giving the DHCPOFFER
