1. A method for performing self-assignment Layer 2 address acquisition implemented by a client device, the method comprising:
selecting a Media Access Control (MAC) address;
generating an outgoing test message that includes a first hash token to test an availability of the selected MAC address, the first hash token comprising a K generation hash (HK) value of a seed known only to the client device, wherein K is an integer value greater than one;
sending the outgoing test message;
determining based on a response to the outgoing test message or a lack of a response to the outgoing test message that the selected MAC address is not in use; and
using the selected MAC address based on the determination that the selected MAC address is not in use.
