Which company owns MAC address prefix F4:91:1E?

MAC address prefix F4:91:1E is registered to ZHUHAI EWPE INFORMATION TECHNOLOGY INC in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with F4:91:1E has a network interface built by ZHUHAI EWPE INFORMATION TECHNOLOGY INC.

What is the OUI F4:91:1E?

F4:91:1E is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to ZHUHAI EWPE INFORMATION TECHNOLOGY INC. It covers every address from F4:91:1E:00:00:00 to F4:91:1E:FF:FF:FF, or 16,777,216 addresses in total. It is also written F4-91-1E.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in F4:91:1E:00:00:00 that is F4:91:1E — 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 ZHUHAI EWPE INFORMATION TECHNOLOGY INC located?

ZHUHAI EWPE INFORMATION TECHNOLOGY INC is listed at Room 409,NO.10,Technology 1st Road, Gangwan Av.,Tangjia Bay Town,Zhuhai,Guangdong,China Zhuhai Guangdong CN 519070 in the IEEE OUI registry entry for F4:91:1E. This is the address the organization registered with the IEEE, which may differ from its current operating address.
