CC:CC:4E is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Sun Fountainhead USA. Corp. It covers every address from CC:CC:4E:00:00:00 to CC:CC:4E:FF:FF:FF, or 16,777,216 addresses in total. It is also written CC-CC-4E.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in CC:CC:4E:00:00:00 that is CC:CC:4E — 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.
