Which company owns MAC address prefix 44:5F:8C?

MAC address prefix 44:5F:8C is registered to Intercel Group Limited in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 44:5F:8C has a network interface built by Intercel Group Limited.

What is the OUI 44:5F:8C?

44:5F:8C is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Intercel Group Limited. It covers every address from 44:5F:8C:00:00:00 to 44:5F:8C:FF:FF:FF, or 16,777,216 addresses in total. It is also written 44-5F-8C.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 44:5F:8C:00:00:00 that is 44:5F:8C — 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 Intercel Group Limited located?

Intercel Group Limited is listed at Unit 6, 17/F, Vanta industrial Centre, New Territories, Hong Kong CN in the IEEE OUI registry entry for 44:5F:8C. This is the address the organization registered with the IEEE, which may differ from its current operating address.
