Which company owns MAC address prefix 7C:C2:C6?

MAC address prefix 7C:C2:C6 is registered to TP-Link Systems Inc in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 7C:C2:C6 has a network interface built by TP-Link Systems Inc.

What is the OUI 7C:C2:C6?

7C:C2:C6 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to TP-Link Systems Inc. It covers every address from 7C:C2:C6:00:00:00 to 7C:C2:C6:FF:FF:FF, or 16,777,216 addresses in total. It is also written 7C-C2-C6.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 7C:C2:C6:00:00:00 that is 7C:C2:C6 — 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 TP-Link Systems Inc located?

TP-Link Systems Inc is listed at 5 Peters Canyon Rd Suit 300 Irvine CA US 92606 in the IEEE OUI registry entry for 7C:C2:C6. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does TP-Link Systems Inc own?

TP-Link Systems Inc holds 46 OUI prefixes in the IEEE registry, of which 7C:C2:C6 is one. A device made by TP-Link Systems Inc could carry a MAC address from any of them.
