Which company owns MAC address prefix F4:9E:CE?

MAC address prefix F4:9E:CE is registered to Sena Technologies Co., Ltd. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with F4:9E:CE has a network interface built by Sena Technologies Co., Ltd..

What is the OUI F4:9E:CE?

F4:9E:CE is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Sena Technologies Co., Ltd.. It covers every address from F4:9E:CE:00:00:00 to F4:9E:CE:FF:FF:FF, or 16,777,216 addresses in total. It is also written F4-9E-CE.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in F4:9E:CE:00:00:00 that is F4:9E:CE — 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 Sena Technologies Co., Ltd. located?

Sena Technologies Co., Ltd. is listed at 19 Heolleung-ro 569-gil, Gangnam-gu Seoul KR 06376 in the IEEE OUI registry entry for F4:9E:CE. This is the address the organization registered with the IEEE, which may differ from its current operating address.
