  • Recovery of Dynamic Host Configuration Protocol IP Addresses
    Publication number: 20140344444
    Abstract: Recovery of an Internet Protocol (IP) address allocated to a client using Dynamic Host Configuration Protocol (DHCP) is provided. Media Access Control (MAC) address and the IP address of the client are stored. When the client is determined as being offline, MAC address and IP address of the client are determined and a DHCP release message carrying the IP address of the client is sent to an address allocation server. The client is determined as being offline based on a shutdown status of a port to which the client is connected. The port may be on the relay device, or an access device that connects the client and the relay device.
