Which company owns MAC address prefix E0:FA:EC?

MAC address prefix E0:FA:EC is registered to Platan sp. z o.o. sp. k. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with E0:FA:EC has a network interface built by Platan sp. z o.o. sp. k..

What is the OUI E0:FA:EC?

E0:FA:EC is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Platan sp. z o.o. sp. k.. It covers every address from E0:FA:EC:00:00:00 to E0:FA:EC:FF:FF:FF, or 16,777,216 addresses in total. It is also written E0-FA-EC.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in E0:FA:EC:00:00:00 that is E0:FA:EC — 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 Platan sp. z o.o. sp. k. located?

Platan sp. z o.o. sp. k. is listed at ul.Platanowa 2 Sopot pomorskie PL 81-855 in the IEEE OUI registry entry for E0:FA:EC. This is the address the organization registered with the IEEE, which may differ from its current operating address.

Platan sp. z o.o. sp. k.

MAC address prefix E0:FA:EC is registered to Platan sp. z o.o. sp. k. in the IEEE OUI registry.
