Abstract

A method and system are disclosed to detect a change in location of a device attached to a communications network including identifying a first address of a device attached to a communications network, identifying the removal of the device from the communications network, identifying when the device is reconnected to the communications network, identifying a second address of the device after the device is reconnected to the communications network, recording the amount of time between the removal and the reconnection of the device with the communication network, evaluating the differences between the first and second addresses, and identifying a change in location of the device as a function of the differences between the first and second addresses.

Claims

1. A method of detecting a change in location of a device attached to a communications network:

(a) identifying a first address of the device;

(b) identifying the removal of the device from the communications network;

(c) identifying when the device is reconnected to the communications network;

(d) identifying a second address of the device after the device is reconnected to the communications network;

(e) recording the amount of time between the removal and the reconnection of the device;

(f) evaluating the differences between the first and second addresses; and

(g) identifying a change in location of the device as a function of the differences between the first and second addresses and the recorded amount of time.

2. The method of claim 1, further comprising recording the amount of time the device is connected to the communication network at the first address and identifying a change in location of the device as a function of the recorded amount of time the device is connected to the communication network at the first address.

3. The method of claim 1, where a change in location of a device is identified if the difference between the first and second addresses exceeds a predetermined threshold.

4. The method of claim 1, further comprising the step of prompting a user of the device to provide the location of the device if a change in location is identified.

5. The method of claim 4, further comprising updating a database with the current location of the device.

6. The method of claim 1, wherein a change in location of a device is identified if the recorded amount of time exceeds a predetermined threshold.

7. The method of claim 3, wherein the predetermined threshold is a function of the recorded time.

8. The method of claim 6, wherein the predetermined threshold is a function of the difference between the first and second addresses.

9. The method of claim 7, wherein the predetermined threshold is inversely proportional to the recorded time.

10. The method of claim 8, wherein the predetermined threshold is inversely proportional to the difference between the first and second addresses.

11. A computer program product for use with a communications network device, said computer program product comprising:

a computer usable medium having computer readable program code modules embodied in said medium for detecting a change in a device attachment on a network;

computer readable first program code module for causing a computer to identify a first address corresponding to the device attached to the network at a first time;

computer readable second program code module for causing the computer to identify a second address corresponding to the device attached to the network at a second time;

computer readable third program code module for causing a computer to compare the first address and the address identifier to determine an address parameter;

computer readable fourth program code module for causing a computer to compare the first time and the second time to determine a temporal parameter; and

computer readable fifth program code module for causing a computer to determine an attachment parameter corresponding to the identity parameter and the temporal parameter.

12. A method of detecting a change in a device attachment on a network, comprising:

(a) identifying a first address corresponding to the device attached to the network at a first time;

(b) identifying a second address corresponding to the device attached to the network at a second time;

(c) comparing the first address and the address identifier to determine an address parameter;

(d) comparing the first time and the second time to determine a temporal parameter; and

(e) determining an attachment parameter corresponding to the identity parameter and the temporal parameter.

13. The method of claim 12, wherein the attachment parameter indicates a change in location of the device.

14. The method of claim 12, wherein the temporal parameter corresponds to the difference between the first time and the second time.

15. The method of claim 12, wherein the first time corresponds to a disconnection of the device from the network.

16. The method of claim 12, wherein the second time corresponds to a reconnection of the device to the network.

17. The method of claim 12, wherein the first time corresponds to an initial connection of the device to the network and the second time corresponds to a disconnection of the device from the network, and the temporal parameter corresponds to the difference between the first time and the second time.

19. The method of claim 13, further comprising:

(a) prompting a user associated with the device to provide a physical location of the device.

20. The method of claim 12, further comprising

(a) updating a database with a location parameter corresponding to the attachment parameter using network address geolocation analysis including at least one of:

whois database lookup, DNS LOC records, domain name geographic indicators, application information, round-trip time approximation, routing data inference.

18. The method of claim 18, wherein determining an attachment parameter includes comparing the address parameter to a predetermined threshold.
