Which company owns MAC address prefix F0:E3:DC?

MAC address prefix F0:E3:DC is registered to Tecon MT, LLC in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with F0:E3:DC has a network interface built by Tecon MT, LLC.

What is the OUI F0:E3:DC?

F0:E3:DC is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Tecon MT, LLC. It covers every address from F0:E3:DC:00:00:00 to F0:E3:DC:FF:FF:FF, or 16,777,216 addresses in total. It is also written F0-E3-DC.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in F0:E3:DC:00:00:00 that is F0:E3:DC — 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 Tecon MT, LLC located?

Tecon MT, LLC is listed at 3rd Khoroshevskaya st - 20 Moscow RU 123298 in the IEEE OUI registry entry for F0:E3:DC. This is the address the organization registered with the IEEE, which may differ from its current operating address.
