The DHCP server informs Artica in real time of the addresses it grants to nodes. A released address is then removed from the section and an address taken by a node is added to this section.
In the left menu, the DHCP > Last computers allows you to display this work.
Note the plus button in the first column. It allows you to add nodes to the Artica database in order to enroll them in other services, such as the possibility of making a node stattic in DHCP, enrolling it in DNS services, etc.
