Simply enter the MAC address for a client device (which you can find on the Device List), into the **MAC Address** field, enter the **IP Address** (and optionally, **Hostname**) you want to assign to this device into those respective fields and click Save. |

As mentioned earlier, Static DHCP offers the mapped IP address (and Hostname) to the MAC address you specified every time it offers a lease. Static DHCP does not prevent a different client from being configured with the same IP address. This is because Static DHCP only offers a static mapping to client devices which request a lease. If another device were to use Static IP, or the router or DHCP were disabled, the other device could take the IP address for itself. Similarly, if the first client for which Static DHCP were then configured for Static IP, it could claim a different IP address than the one in FreshTomato' | As mentioned earlier, Static DHCP offers the mapped IP address (and Hostname) to the MAC address you specified every time it offers a lease.
