Hostnames not showing in ARP Table

[ARAMP1]

I've assigned static IP addresses to most of the things on my home network.  How do I get the hostnames to display in the ARP table?  I've done a search here and come up short.  All the devices that are dynamically assigned are showing.

Arp tables don't show host names.  They only show IP to MAC address mappings.

Then why is there a column for them?  And why does it show them for the automatically assigned IP addresses?

That's an arp table maintained withing pfsense.  It's not the arp cache as used by freeBSD.  Go to a command prompt and enter the command "arp -a", which will show the contents of the arp cache.  If a host name is there, it's because something did a host lookup on the IP address.  An arp cache is used when trying to reach an IP address on the local net, by providing the MAC address for it.  A host name has nothing to do with that function.
