Which company owns MAC address prefix CC:CC:EA?

MAC address prefix CC:CC:EA is registered to Phoenix Contact GmbH & Co. KG in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with CC:CC:EA has a network interface built by Phoenix Contact GmbH & Co. KG.

What is the OUI CC:CC:EA?

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

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in CC:CC:EA:00:00:00 that is CC:CC:EA — 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 Phoenix Contact GmbH & Co. KG located?

Phoenix Contact GmbH & Co. KG is listed at Dringenauer Str. 30 Bad Pyrmont - DE D-31812 in the IEEE OUI registry entry for CC:CC:EA. This is the address the organization registered with the IEEE, which may differ from its current operating address.
