What is the OUI 6C:2A:CB?

6C:2A:CB is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Paxton Access Ltd. It covers every address from 6C:2A:CB:00:00:00 to 6C:2A:CB:FF:FF:FF, or 16,777,216 addresses in total. It is also written 6C-2A-CB.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 6C:2A:CB:00:00:00 that is 6C:2A: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 Paxton Access Ltd located?

Paxton Access Ltd is listed at Paxton House Brighton East Sussex GB BN1 9HU in the IEEE OUI registry entry for 6C:2A:CB. This is the address the organization registered with the IEEE, which may differ from its current operating address.
