Which company owns MAC address prefix 60:10:A2?

MAC address prefix 60:10:A2 is registered to Crompton Instruments in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 60:10:A2 has a network interface built by Crompton Instruments.

What is the OUI 60:10:A2?

60:10:A2 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Crompton Instruments. It covers every address from 60:10:A2:00:00:00 to 60:10:A2:FF:FF:FF, or 16,777,216 addresses in total. It is also written 60-10-A2.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 60:10:A2:00:00:00 that is 60:10:A2 — 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 Crompton Instruments located?

Crompton Instruments is listed at 12 Freebournes Road Witham Essex GB CM8 3AH in the IEEE OUI registry entry for 60:10:A2. This is the address the organization registered with the IEEE, which may differ from its current operating address.
