Which company owns MAC address prefix F0:4B:F2?

MAC address prefix F0:4B:F2 is registered to JTECH Communications, Inc. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with F0:4B:F2 has a network interface built by JTECH Communications, Inc..

What is the OUI F0:4B:F2?

F0:4B:F2 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to JTECH Communications, Inc.. It covers every address from F0:4B:F2:00:00:00 to F0:4B:F2:FF:FF:FF, or 16,777,216 addresses in total. It is also written F0-4B-F2.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in F0:4B:F2:00:00:00 that is F0:4B:F2 — 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 JTECH Communications, Inc. located?

JTECH Communications, Inc. is listed at 6413 Congress Ave. Boca Raton FL US 33487 in the IEEE OUI registry entry for F0:4B:F2. This is the address the organization registered with the IEEE, which may differ from its current operating address.
