What is the OUI CC:73:14?

CC:73:14 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to HONG KONG WHEATEK TECHNOLOGY LIMITED. It covers every address from CC:73:14:00:00:00 to CC:73:14:FF:FF:FF, or 16,777,216 addresses in total. It is also written CC-73-14.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in CC:73:14:00:00:00 that is CC:73:14 — and look that prefix up in the IEEE OUI registry. If the second-lowest bit of the first octet is set, the address is locally administered (a randomized or private MAC), which belongs to no manufacturer and will not resolve; modern phones and laptops use these by default on each network.
