Which company owns MAC address prefix E4:C8:06?

MAC address prefix E4:C8:06 is registered to Ceiec Electric Technology Inc. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with E4:C8:06 has a network interface built by Ceiec Electric Technology Inc..

What is the OUI E4:C8:06?

E4:C8:06 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Ceiec Electric Technology Inc.. It covers every address from E4:C8:06:00:00:00 to E4:C8:06:FF:FF:FF, or 16,777,216 addresses in total. It is also written E4-C8-06.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in E4:C8:06:00:00:00 that is E4:C8:06 — 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 Ceiec Electric Technology Inc. located?

Ceiec Electric Technology Inc. is listed at 8/F West Side, Building 201, Terra Industrial & Tradepark, Che Gong Miao, Shenzhen Guangdong CN 518040 in the IEEE OUI registry entry for E4:C8:06. This is the address the organization registered with the IEEE, which may differ from its current operating address.
