Got to Hardware Inventory of the relays in question and look at the "Network Adapter Configuration" section and see if the assigned IP is listed among the numerous adapters.
The IP listed on general page is the routing IP the Parent sees...
The network adapter configuration information is part of the bizarre.
For instance, if you have a device group of all relays, all relays reporting to the IFR;s have the F5 IP address in the IP Address column.
But, if you look under the relay's c, the "Host IP Address" is correctly identified.
I would have expected, until now, that the identity.ini would have the IP address in the network adapter configuration, but apparently not.
We're excelling at odd.
