IP Setup 6-27
An IP address is marked declined when a client to whom the DHCP server offers the address declines the address. A client declines an address if it determines that a leased address is already in use by another device.
Selecting Include restores the selected IP address to the address serving pool so that the IP address is once again eligible to be served to a client.
•Release is displayed if the entry is currently offered, leased, or reserved.
Selecting Release puts the selected entry in the available state. You will be presented with a warning dialog asking you to confirm the operation since the IP address is in use. There is no mechanism to notify the client to whom the address is leased that the lease has been terminated. Thus, the client will continue to use the address until the next time it attempts to renew its lease. In the interim, the server may lease the same IP address to a different client, thereby creating an address conflict. For this reason, releasing an address that is actively being used by a client is generally not recommended.
•Reserve… is displayed if the entry is available, declined, excluded, leased, offered, or reserved.
Reserving an IP address for a client with a particular Ethernet MAC address guarantees that a client with the specified MAC address will be offered or leased the specified IP address. Moreover, it prevents the specified IP address from being offered or leased to any other client.

The gateway’s Ethernet IP address(es) will be automatically excluded from the address serving pool(s) on startup. Entries in the served IP address list corresponding to the gateway’s Ethernet IP address(es) that have been automatically excluded on startup are not selectable.
