Abstract

A network device is configured to receive a request, from a user device, for an IP address; assign the IP address to the user device; assign an amount of time that the IP address may be used by the user device; send the IP address to the user device; determine that the amount of time has expired; determine that the user device is idle; assign a new IP address to the user device after the amount of time has expired and when the user device is idle; send the new IP address to the user device; and assign a new amount of time that the new IP address may be used by the user device.

Claims

1. A method comprising:

receiving, by a network device, a request from a user device for an IP address;

assigning, by the network device, the IP address to the user device;

assigning, by the network device, an amount of time that the IP address may be used by the user device, the amount of time being finite;

sending, by the network device, the IP address to the user device;

determining, by the network device, that the amount of time has expired;

determining, by the network device, that the user device is idle;

assigning, by the network device, a new IP address to the user device, after the amount of time has expired and when the user device is idle; and

sending, by the network device, the new IP address to the user device.

2. The method of claim 1, further comprising:

sending, by the network device, the IP address, the amount of time, and a name for the user device to a memory device, the memory device associating the name for the user device with the IP address and the amount of time for the IP address.

3. The method of claim 1, where determining that the user device is idle, includes determining that the user device is not sending messages, through a network, with the IP address assigned to the user device.

4. The method of claim 1, further comprises:

assigning, by the network device, a new amount of time that the new IP address may be used by the user device.

5. A method comprising:

receiving, by a network device, a request from a user device for an IP address;

assigning, by the network device, the IP address to the user device;

assigning, by the network device and to the IP address, an amount of time that the IP address may be used by the user device;

sending, by the network device, the IP address to the user device;

determining, by the network device, that the amount of time has expired;

receiving, by the network device, a second request from the user device for the IP address, after the amount of time has expired;

assigning, by the network device, a new IP address to the user device, after the amount of time has expired; and

sending, by the network device, the new IP address to the user device.

6. The method of claim 5, where receiving the second request from the user device for the IP address, is based on generation of the second request when the user device turns on.

7. The method of claim 5, further comprising:

sending, by the network device, the IP address and the new IP address, for the user device, and a name for the user device for storage at a memory device.

8. The method of claim 5, further comprising:

preventing, by the network device, the user device from receiving the IP address after the amount of time has expired.

9. The method of claim 5, where assigning the IP address to the user device includes:

sending an authentication request to a server, the server authenticating that the user device is authorized to access a network;

receiving an authentication result, from the server, that the user device is authorized to access the network; and

assigning the IP address to the user device based on receiving the authentication result.

10. The method of claim 5, further comprising:

assigning, by the network device, a new amount of time that the new IP address may be used by the user device.

11. A system comprising:

a network device to;

receive, from a user device, a request for an IP address;

assign the IP address to the user device;

assign an amount of time that the IP address may be used by the user device;

send the IP address to the user device;

determine that the amount of time has expired;

determine that the user device is idle;

assign a new IP address to the user device after the amount of time has expired and when the user device is idle;

send the new IP address to the user device; and

assign a new amount of time that the new IP address may be used by the user device.

12. The system of claim 11, where, when assigning the IP address to the user device, the network device is to:

send information associated with the user device to a server for authenticating that the user device is authorized to access a network;

receive a message from the server that the user device is authorized to access the network; and

assign the IP address to the user device based on receiving the authentication result.

13. The system of claim 11, where, when determining that the user device is idle, the network device is to determine that the user device is not sending any messages, through a network, over a period of time, with the IP address assigned to the user device.

14. The system of claim 11, where the network device is further to:

send the IP address, the amount of time, and a name for the user device to a memory device, the memory device associating the name for the user device with the IP address and the amount of time for the IP address.

15. The system of claim 14, where the network device is further to:

receive a message from the memory device that the amount of time has expired.

16. A system comprising:

a network device to;

receive a request for an IP address for a user device;

assign the IP address to the user device;

assign an amount of time to the IP address;

receive a second request for a new IP address for the user device after the amount of time is expired;

assign a new IP address to the user device based on receiving the second request;

send the new IP address to the user device; and

assign a new amount of time to the new IP address.

17. The system of claim 16, where the network device is further to:

store the IP address, the amount of time, and a name for the user device; and

associate the name for the user device with the IP address and the amount of time.

18. The system of claim 16, where, when assigning the IP address to the user device, the network device is to:

receive a request to authenticate that the user device is authorized to access a network;

authenticate that the user device is authorized to access the network; and

assign the IP address to the user device based on receiving the authentication result.

19. The system of claim 16, where the IP address is associated with a geographic region for the network device that is different than a geographic region associated with the user device.

20. The system of claim 16, where, when assigning the IP address and the new IP address to the user device, the network device is to obtain the IP address and the new IP address from a list of IP addresses stored in the network device.
