1. A method of dynamic allocation of a network address to a network device from an address server associated with a virtual subnet comprising the steps of:
- broadcasting an address server query message by the network device to the address server associated with the virtual subnet;
receiving at the network device from the address server the server network address identifying the address server associated with the virtual subnet; and
transmitting an address request message to the address server identified by the server network address.

Abstract
A method, apparatus, and system for dynamic allocation of a network address associated with a virtual subnet (302) to a network device (100) having a transceiver (102) coupled to a network (304) for broadcasting an address server query message (602) in response to initialization of the network device (100) and an address server (200) coupled to the network (304) sending the network address associated with a virtual subnet (302) to the network device (100) in response to the address server (200) receiving the address server query message (602).

10. An apparatus for dynamic allocation of a network address to a network device from an address server associated with a virtual subnet comprising:
-
a transceiver located in the network device coupled to a network requesting the network address to be assigned to the network device by broadcasting an address server query message to the address server associated with the virtual subnet;
a memory located in the network device coupled to the transceiver for storing the server network address within a response message received by the transceiver from the address server associated with the virtual subnet;
a processor located at the network device coupled to the memory and the transceiver for identifying whether the server network address received within the response message is the server network address of the address server associated with the virtual subnet; and
wherein the transceiver transmits an address request message to the address server in response to the processor identifying the server network address. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)

18. A system for dynamic allocation of a network address in a network comprising:
-
a network device having a transceiver coupled to the network broadcasting an address server query message in response to initialization of the network device;
an address server having a server network address coupled to the network sending the server network address to the network device in response to the address server receiving the address server query message;
a memory located in the network device coupled to the transceiver for storing the server network address in response to the transceiver receiving the server network address;
wherein address server sending said server network address within a server introduction message; and
a processor located in the network device coupled to the memory and the transceiver for determining if the address server is associated with the virtual subnet and transmitting a network address request message to the address server in response to receiving the server introduction message. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25)
