Which company owns MAC address prefix CC:CD:64?

MAC address prefix CC:CD:64 is registered to SM-Electronic GmbH in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with CC:CD:64 has a network interface built by SM-Electronic GmbH.

What is the OUI CC:CD:64?

CC:CD:64 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to SM-Electronic GmbH. It covers every address from CC:CD:64:00:00:00 to CC:CD:64:FF:FF:FF, or 16,777,216 addresses in total. It is also written CC-CD-64.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in CC:CD:64:00:00:00 that is CC:CD:64 — 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.

Where is SM-Electronic GmbH located?

SM-Electronic GmbH is listed at Waldweg 2 Stapelfeld / Braak DE 22145 in the IEEE OUI registry entry for CC:CD:64. This is the address the organization registered with the IEEE, which may differ from its current operating address.
