Dynamic local media access control (MAC) address assignment

1. A device comprising: at least one processor configured to:

initiate a link establishment with a network device;

determine whether a previously assigned media access control (MAC) address is stored locally;

transmit a message to the network device requesting validation of the previously assigned MAC address when stored locally; and

communicate using the previously assigned MAC address when the validation is received from the network device, otherwise:

transmit a request for a range of MAC addresses that includes a dynamically assigned MAC address;

receive, from the network device, the range of MAC addresses;

distribute the range of MAC addresses, exclusive of the dynamically assigned MAC address, to additional devices; and

communicate using the dynamically assigned MAC address received from the network device.

2. The device of claim 1 , wherein the link establishment comprises autonegotiation.

3. The device of claim 2 , wherein the dynamically assigned MAC address is received from the network device via an autonegotiation page during the link establishment.

4. The device of claim 3 , wherein the at least one processor is further configured to:

transmit a request for the dynamically assigned MAC address via another autonegotiation page.

5. The device of claim 4 , wherein the autonegotiation page and the another autonegotiation page each comprises at least one of a base page or a next page.

6. The device of claim 1 , wherein the dynamically assigned MAC address is generated from a 24-bit random value and a pre-configured 24-bit value, wherein the 24-bit random value comprises least significant bits of the dynamically assigned MAC address and the pre-configured 24-bit value comprises most significant bits of the dynamically assigned MAC address.

7. The device of claim 1 , wherein the dynamically assigned MAC address is unique to a local area network that the device is associated with.

8. A method comprising:

initiating a link establishment with a network device;

determining whether a previously assigned media access control (MAC) address is stored locally;

transmitting a message to the network device requesting validation of the previously assigned MAC address when stored locally; and

communicating using the previously assigned MAC address when the validation is received from the network device, otherwise:

transmitting a request for a range of MAC addresses that includes a dynamically assigned MAC address;

receiving, from the network device, the range of MAC addresses;

distributing the range of MAC addresses, exclusive of the dynamically assigned MAC address, to additional devices; and

communicating using the dynamically assigned MAC address received from the network device.

9. The method of claim 8 , wherein the MAC address is received from the network device in an autonegotiation page.

10. The method of claim 9 , further comprising:

transmitting a request for the dynamically assigned MAC address via another autonegotiation page.

11. The method of claim 10 , wherein the autonegotiation page and the another autonegotiation page each comprises at least one of a base page or a next page.

12. The method of claim 8 , wherein the link establishment comprises autonegotiation.

13. The method of claim 8 , wherein the dynamically assigned MAC address is generated from a 24-bit random value and a pre-configured 24-bit value, wherein the 24-bit random value comprises least significant bits of the dynamically assigned MAC address and the pre-configured 24-bit value comprises most significant bits of the dynamically assigned MAC address.

14. The method of claim 8 , wherein the dynamically assigned MAC address comprises a locally unique MAC address.

15. A non-transitory computer-readable medium comprising code that, when executed by one or more processors, causes the one or more processors to perform operations, and the code comprising:

code to initiate a link establishment with a network device;

code to determine whether a previously assigned media access control (MAC) address is stored locally;

code to transmit a message to the network device requesting validation of the previously assigned MAC address when stored locally; and

code to communicate using the previously assigned MAC address when the validation is received from the network device,

otherwise to transmit a request for a range of MAC addresses that includes a dynamically assigned MAC address;

receive, from the network device, the range of MAC addresses;

distribute the range of MAC addresses, exclusive of the dynamically assigned MAC address, to additional devices; and

communicate using the dynamically assigned MAC address received from the network device.

16. The non-transitory computer-readable medium of claim 15 , wherein the dynamically assigned MAC address is received from the network device during the link establishment in response to a request for the dynamically assigned MAC address transmitted to the network device via an autonegotiation page.

17. The non-transitory computer-readable medium of claim 16 , wherein the link establishment comprises autonegotiation and the MAC address is received from the network device in another autonegotiation page.

18. The non-transitory computer-readable medium of claim 17 , wherein the autonegotiation page and the another autonegotiation page each comprises at least one of a base page or a next page.

19. The non-transitory computer-readable medium of claim 15 , wherein the dynamically assigned MAC address is generated from a 24-bit random value and a pre-configured 24-bit value, wherein the 24-bit random value comprises least significant bits of the dynamically assigned MAC address and the pre-configured 24-bit value comprises most significant bits of the dynamically assigned MAC address.

20. The device of claim 2 , wherein the autonegotiation of the link establishment occurs at a physical layer of the device.
