Abstract: Relay functionality may be provided. A network device may receive a response packet and may determine that one of Option-82 and Option-18 information is not present in the received response packet. Next, in response to determining that one of Option-82 and Option-18 information is not present in the received response packet, a database may be queried for information associated with the response packet. Then, based on the information associated with the response packet, the response packet may be sent to a client device associated with the response packet.
