…ature This splits the Neighbors menu item in an existing static assignments and adds the automatic discovery feature which includes logging and insights into the currently known hosts on the network. When automatic discovery is disabled, it drops back to arp/ndp. By default automatic mode is enabled on all interfaces, but configuration options exists (to limit interfaces and networks). Other consumers which require host mappings can use the /usr/local/opnsense/scripts/interfaces/list_hosts.py script to either fetch the sqlite database or arp/ndp data for the selected pprotocol(s).
