Which company owns MAC address prefix C8:68:DE?

MAC address prefix C8:68:DE is registered to Huawei Device Co., Ltd. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with C8:68:DE has a network interface built by Huawei Device Co., Ltd..

What is the OUI C8:68:DE?

C8:68:DE is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Huawei Device Co., Ltd.. It covers every address from C8:68:DE:00:00:00 to C8:68:DE:FF:FF:FF, or 16,777,216 addresses in total. It is also written C8-68-DE.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in C8:68:DE:00:00:00 that is C8:68:DE — 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 Huawei Device Co., Ltd. located?

Huawei Device Co., Ltd. is listed at No.2 of Xincheng Road, Songshan Lake Zone Dongguan Guangdong CN 523808 in the IEEE OUI registry entry for C8:68:DE. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does Huawei Device Co., Ltd. own?

Huawei Device Co., Ltd. holds 660 OUI prefixes in the IEEE registry, of which C8:68:DE is one. A device made by Huawei Device Co., Ltd. could carry a MAC address from any of them.
