Which company owns MAC address prefix E0:05:C5?

MAC address prefix E0:05:C5 is registered to TP-LINK TECHNOLOGIES CO.,LTD. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with E0:05:C5 has a network interface built by TP-LINK TECHNOLOGIES CO.,LTD..

What is the OUI E0:05:C5?

E0:05:C5 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to TP-LINK TECHNOLOGIES CO.,LTD.. It covers every address from E0:05:C5:00:00:00 to E0:05:C5:FF:FF:FF, or 16,777,216 addresses in total. It is also written E0-05-C5.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in E0:05:C5:00:00:00 that is E0:05:C5 — 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 TECHNOLOGIES CO.,LTD. located?

TP-LINK TECHNOLOGIES CO.,LTD. is listed at Building 7, Second Part, Honghualing Industrial Zone Shenzhen Guangdong CN 518000 in the IEEE OUI registry entry for E0:05:C5. This is the address the organization registered with the IEEE, which may differ from its current operating address.
