The behavior of the IPv4 DHCP server iscontrolled there, along with static IP address mappings and related options suchas static ARP. To alter the behavior of the IPv4 DHCP server, navigate to Services > DHCPServer in the web interface. Both the -Mac and the -DhcpSite switches work on wildcard matches so you won’t need the full address or full name of the DHCP server. If you have a large enterprise network, comprises of multiple AD sites, then you can narrow the field down with the -DhcpSite together with the DNS name of your DHCP server in that site. The Dynamic Host Configuration Protocol (DHCP) is a network management protocol used on Internet Protocol (IP) networks, whereby a DHCP server dynamically assigns an IP address and other network configuration parameters to each device on the network, so they can communicate with other IP networks. You can also add static leases to issue a specific IP address to a particular client (identified by MAC address). The issued leases are showed here as dynamic entries.
