A DHCP reservation is necessary if either you want to assign a specific IP address to a specific client, or you have enabled the setting Only Allow Known MAC Addresses. If this setting is enabled, only clients added to the DHCP Reservation table with their MAC address will be able to use the DHCP service. For more information, see How to Configure DHCP to Assign IPs to Known MAC Addresses.
Before You Begin
