Which company owns MAC address prefix 94:DC:4E?

MAC address prefix 94:DC:4E is registered to AEV, spol. s r. o. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 94:DC:4E has a network interface built by AEV, spol. s r. o..

What is the OUI 94:DC:4E?

94:DC:4E is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to AEV, spol. s r. o.. It covers every address from 94:DC:4E:00:00:00 to 94:DC:4E:FF:FF:FF, or 16,777,216 addresses in total. It is also written 94-DC-4E.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 94:DC:4E:00:00:00 that is 94:DC:4E — 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 AEV, spol. s r. o. located?

AEV, spol. s r. o. is listed at Jozky Silneho 2783/9 Kromeriz CZ 76701 in the IEEE OUI registry entry for 94:DC:4E. This is the address the organization registered with the IEEE, which may differ from its current operating address.
