 DHCP Reservation is a simple way to ensure that FreshTomato offers certain client devices the same IP address each time they request a lease. Simply enter the MAC address for a client device (found in [[status-devices|Device List]]), into the **MAC Address** field, enter the **IP Address** (and optionally, **Hostname**) you want to assign into the appropriate fields and click "Save". DHCP Reservation is a simple way to ensure that FreshTomato offers certain client devices the same IP address each time they request a lease.

 Traditionally, devices were identified within DHCP by a //hardware type// code and //a client hardware (MAC) address//. Later, the optional Hostname field allowed more freedom when mapping device names in DHCP.
