Abstract

A method for Internet Protocol (IP) device discovery implemented in a control network having a gateway device, a router, and an IP device at a location. A location management system including a IP device at a location having an IP address assigned by a router at the location. A gateway device for managing a set of two or more local management devices at a location.

2 . The method of claim 1 , wherein the one or more values comprises at least one of:

a value within a subnet indicated by the first network address, a portion of an internet protocol address, one or more values subsequent to a last dotted decimal of the first network address, or one or more values at an end of the first network address.

3 . The method of claim 1 , wherein the determining at least the second network address of the plurality of network addresses comprises determining at least the second network address based on at least one of: determining a subset of the plurality of network addresses, applying a mathematical operation to the at least a portion of the one or more values, performing an addition operation associated with least a portion of the one or more values, subtracting a number from at least a portion of the one or more values, or performing a multiplication operation associated with at least a portion of the one or more values.

4 . The method of claim 1 , wherein the second network address comprises at least one of an identifier assigned to the second device, a media access control address, an ethernet address, or an internet protocol address.

5 . The method of claim 1 , wherein the first network address comprises an internet protocol address and the second network address comprises an internet protocol address.

6 . The method of claim 1 , further comprising determining, based on comparing a media access control address stored by the first device and a media access control address received in the second message, to communicate with the second device.

7 . The method of claim 1 , wherein sending the first message comprises at least one of broadcasting a message comprising the second network address, querying the second network address, or sending an address resolution protocol message comprising the second network address.

8 . A device comprising:

one or more processors; and

memory storing instructions that when executed by the one or more processors, cause the device to:

determine, at a premises and based on one or more values in a first network address assigned to the device, at least a second network address of a plurality of network addresses;

send, based on the second network address, a first message;

receive, from a second device located at the premises, a second message responsive to the first message; and

communicate, based on the second network address being assigned to the second device, with the second device.

9 . The device of claim 8 , wherein the one or more values comprises at least one of: a value within a subnet indicated by the first network address, a portion of an internet protocol address, one or more values subsequent to a last dotted decimal of the first network address, or one or more values at an end of the first network address.

10 . The device of claim 8 , wherein the instructions that, when executed by the one or more processors, cause the device to determine at least the second network address of the plurality of network addresses comprises instructions that, when executed by the one or more processors, cause the device to at least one of: determine a subset of the plurality of network addresses, apply a mathematical operation to the at least a portion of the one or more values, perform an addition operation associated with least a portion of the one or more values, subtract a number from at least a portion of the one or more values, or perform a multiplication operation associated with at least a portion of the one or more values.

11 . The device of claim 8 , wherein the second network address comprises at least one of an identifier assigned to the second device, a media access control address, an ethernet address, or an internet protocol address.

12 . The device of claim 8 , wherein the first network address comprises an internet protocol address and the second network address comprises an internet protocol address.

13 . The device of claim 8 , wherein the instructions, when executed by the one or more processors, further cause the device to determine, based on comparing a media access control address stored by the device and a media access control address received in the second message, to communicate with the second device.

14 . The device of claim 8 , wherein the instructions that, when executed by the one or more processors, cause the device to send the first message comprises instructions that, when executed by the one or more processors, cause the device to at least one of broadcast a message comprising the second network address, query the second network address, or send an address resolution protocol message comprising the second network address.

15 . A non-transitory computer-readable medium storing instructions that, when executed, cause:

determining, by a first device located at a premises and based on one or more values in a first network address assigned to the first device, at least a second network address of a plurality of network addresses;

sending, by the first device and based on the second network address, a first message;

receiving, by the first device and from a second device located at the premises, a second message responsive to the first message; and

communicating, by the first device and based on the second network address being assigned to the second device, with the second device.

16 . The non-transitory computer-readable medium of claim 15 , wherein the one or more values comprises at least one of: a value within a subnet indicated by the first network address, a portion of an internet protocol address, one or more values subsequent to a last dotted decimal of the first network address, or one or more values at an end of the first network address.

17 . The non-transitory computer-readable medium of claim 15 , wherein the determining at least the second network address of the plurality of network addresses comprises determining at least the second network address based on at least one of: determining a subset of the plurality of network addresses, applying a mathematical operation to the at least a portion of the one or more values, performing an addition operation associated with least a portion of the one or more values, subtracting a number from at least a portion of the one or more values, or performing a multiplication operation associated with at least a portion of the one or more values.

18 . The non-transitory computer-readable medium of claim 15 , wherein the second network address comprises at least one of an identifier assigned to the second device, a media access control address, an ethernet address, or an internet protocol address.

19 . The non-transitory computer-readable medium of claim 15 , wherein the first network address comprises an internet protocol address and the second network address comprises an internet protocol address.

20 . The non-transitory computer-readable medium of claim 15 , further comprising determining, based on comparing a media access control address stored by the first device and a media access control address received in the second message, to communicate with the second device.

21 . The non-transitory computer-readable medium of claim 15 , wherein sending the first message comprises at least one of broadcasting a message comprising the second network address querying the second network address, or sending an address resolution protocol message comprising the second network address.

22 . A system comprising:

a first device and a second device located at a premises, wherein the first device is configured to:

determine, based on one or more values in a first network address assigned to the first device, at least a second network address of a plurality of network addresses;

send, based on the second network address, a first message;

receive, from the second device, a second message responsive to the first message; and

communicate, based on the second network address being assigned to the second device, with the second device.

23 . The system of claim 22 , wherein the one or more values comprises at least one of:
