Which company owns MAC address prefix F8:46:2D?

MAC address prefix F8:46:2D is registered to SYNTEC Incorporation in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with F8:46:2D has a network interface built by SYNTEC Incorporation.

What is the OUI F8:46:2D?

F8:46:2D is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to SYNTEC Incorporation. It covers every address from F8:46:2D:00:00:00 to F8:46:2D:FF:FF:FF, or 16,777,216 addresses in total. It is also written F8-46-2D.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in F8:46:2D:00:00:00 that is F8:46:2D — 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 SYNTEC Incorporation located?

SYNTEC Incorporation is listed at 3F, NO.105, Shing-shyue St., Hsinchu TW 300 in the IEEE OUI registry entry for F8:46:2D. This is the address the organization registered with the IEEE, which may differ from its current operating address.
