Which company owns MAC address prefix F0:B6:EB?

MAC address prefix F0:B6:EB is registered to Poslab Technology Co., Ltd. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with F0:B6:EB has a network interface built by Poslab Technology Co., Ltd..

What is the OUI F0:B6:EB?

F0:B6:EB is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Poslab Technology Co., Ltd.. It covers every address from F0:B6:EB:00:00:00 to F0:B6:EB:FF:FF:FF, or 16,777,216 addresses in total. It is also written F0-B6-EB.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in F0:B6:EB:00:00:00 that is F0:B6:EB — 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 Poslab Technology Co., Ltd. located?

Poslab Technology Co., Ltd. is listed at 5F-1, No.490 Bannan Rd. Jhonghe City TW 235 in the IEEE OUI registry entry for F0:B6:EB. This is the address the organization registered with the IEEE, which may differ from its current operating address.
