Which company owns MAC address prefix C4:01:CE?

MAC address prefix C4:01:CE is registered to PRESITION (2000) CO., LTD. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with C4:01:CE has a network interface built by PRESITION (2000) CO., LTD..

What is the OUI C4:01:CE?

C4:01:CE is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to PRESITION (2000) CO., LTD.. It covers every address from C4:01:CE:00:00:00 to C4:01:CE:FF:FF:FF, or 16,777,216 addresses in total. It is also written C4-01-CE.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in C4:01:CE:00:00:00 that is C4:01:CE — 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 PRESITION (2000) CO., LTD. located?

PRESITION (2000) CO., LTD. is listed at 42/6 Moo6 Muang Samutsakorn TH 74000 in the IEEE OUI registry entry for C4:01:CE. This is the address the organization registered with the IEEE, which may differ from its current operating address.
