Which company owns MAC address prefix 1C:27:04?

MAC address prefix 1C:27:04 is registered to zte corporation in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 1C:27:04 has a network interface built by zte corporation.

What is the OUI 1C:27:04?

1C:27:04 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to zte corporation. It covers every address from 1C:27:04:00:00:00 to 1C:27:04:FF:FF:FF, or 16,777,216 addresses in total. It is also written 1C-27-04.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 1C:27:04:00:00:00 that is 1C:27:04 — 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 zte corporation located?

zte corporation is listed at 12/F.,zte R&D building ,kejinan Road,Shenzhen,P.R.China shenzhen guangdong CN 518057 in the IEEE OUI registry entry for 1C:27:04. This is the address the organization registered with the IEEE, which may differ from its current operating address.
