Which company owns MAC address prefix 24:5C:CB?

MAC address prefix 24:5C:CB is registered to AXIe Consortium, Inc. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 24:5C:CB has a network interface built by AXIe Consortium, Inc..

What is the OUI 24:5C:CB?

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

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 24:5C:CB:00:00:00 that is 24:5C:CB — 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 AXIe Consortium, Inc. located?

AXIe Consortium, Inc. is listed at P.O. Box 1016 Niwot CO US 80544-1016 in the IEEE OUI registry entry for 24:5C:CB. This is the address the organization registered with the IEEE, which may differ from its current operating address.
