Which company owns MAC address prefix 14:5E:45?

MAC address prefix 14:5E:45 is registered to Bamboo Systems Group in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 14:5E:45 has a network interface built by Bamboo Systems Group.

What is the OUI 14:5E:45?

14:5E:45 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Bamboo Systems Group. It covers every address from 14:5E:45:00:00:00 to 14:5E:45:FF:FF:FF, or 16,777,216 addresses in total. It is also written 14-5E-45.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 14:5E:45:00:00:00 that is 14:5E:45 — 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 Bamboo Systems Group located?

Bamboo Systems Group is listed at Sheraton House, Castle Park Cambridge CAMBRIDGESHIRE GB CB3 0AX in the IEEE OUI registry entry for 14:5E:45. This is the address the organization registered with the IEEE, which may differ from its current operating address.
