If multiple DHCP servers are active in a network, the stations "divide" themselves equally between them. However, the DNS server in devices can only properly resolve the name of the station which was assigned the address information by the DHCP server. In order for the DNS server to be able to resolve the names of other DHCP servers, these can be operated in a cluster. In this operating mode, the DHCP server monitors all DHCP negotiations in the network. It additionally supplements its table with the stations which are registered at the other DHCP servers in the cluster.
Activate the setting for the DHCP cluster under in the settings for the DHCP networks.
