Which company owns MAC address prefix F0:97:E5?

MAC address prefix F0:97:E5 is registered to TAMIO, INC in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with F0:97:E5 has a network interface built by TAMIO, INC.

What is the OUI F0:97:E5?

F0:97:E5 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to TAMIO, INC. It covers every address from F0:97:E5:00:00:00 to F0:97:E5:FF:FF:FF, or 16,777,216 addresses in total. It is also written F0-97-E5.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in F0:97:E5:00:00:00 that is F0:97:E5 — 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 TAMIO, INC located?

TAMIO, INC is listed at 12F-2, No.33, Sec. 1 , Mingsheng Rd.,Banqiao Dist New Taipei City TW 22069 in the IEEE OUI registry entry for F0:97:E5. This is the address the organization registered with the IEEE, which may differ from its current operating address.
