Which company owns MAC address prefix EC:9E:68?

MAC address prefix EC:9E:68 is registered to Anhui Taoyun Technology Co., Ltd in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with EC:9E:68 has a network interface built by Anhui Taoyun Technology Co., Ltd.

What is the OUI EC:9E:68?

EC:9E:68 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Anhui Taoyun Technology Co., Ltd. It covers every address from EC:9E:68:00:00:00 to EC:9E:68:FF:FF:FF, or 16,777,216 addresses in total. It is also written EC-9E-68.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in EC:9E:68:00:00:00 that is EC:9E:68 — 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 Anhui Taoyun Technology Co., Ltd located?

Anhui Taoyun Technology Co., Ltd is listed at 6/F and 23/F, Scientific Research Building, Building 2, Zone A, China Sound Valley, No. 3333, Xiyou Road, High tech Zone Hefei Anhui Hefei Anhui CN 230094 in the IEEE OUI registry entry for EC:9E:68. This is the address the organization registered with the IEEE, which may differ from its current operating address.
