Which company owns MAC address prefix 08:81:B2?

MAC address prefix 08:81:B2 is registered to Logitech (China) Technology Co., Ltd in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 08:81:B2 has a network interface built by Logitech (China) Technology Co., Ltd.

What is the OUI 08:81:B2?

08:81:B2 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Logitech (China) Technology Co., Ltd. It covers every address from 08:81:B2:00:00:00 to 08:81:B2:FF:FF:FF, or 16,777,216 addresses in total. It is also written 08-81-B2.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 08:81:B2:00:00:00 that is 08:81:B2 — 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 Logitech (China) Technology Co., Ltd located?

Logitech (China) Technology Co., Ltd is listed at 1111 Changshou Road Shanghai CN 200001 in the IEEE OUI registry entry for 08:81:B2. This is the address the organization registered with the IEEE, which may differ from its current operating address.
