After an IP address is leased to a client, only that client may release the address. FTOS performs a IP +
MAC source address validation to ensure that no client can release another clients address. This is a default
behavior, and is separate from IP+MAC source address validation. For more information, refer to IP+MAC
Source Address Validation on page 185.
