Which company owns MAC address prefix 34:A2:7D?

MAC address prefix 34:A2:7D is registered to Unisyue Technologies Co;LTD in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 34:A2:7D has a network interface built by Unisyue Technologies Co;LTD.

What is the OUI 34:A2:7D?

34:A2:7D is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Unisyue Technologies Co;LTD. It covers every address from 34:A2:7D:00:00:00 to 34:A2:7D:FF:FF:FF, or 16,777,216 addresses in total. It is also written 34-A2-7D.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 34:A2:7D:00:00:00 that is 34:A2:7D — 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 Unisyue Technologies Co;LTD located?

Unisyue Technologies Co;LTD is listed at Room 402, No. 2 Building, NO.1 ZhongGuancun East Rd, HaiDian District,Beijing, People’s Republic of ChinaBeijing, Beijing CN 100190 in the IEEE OUI registry entry for 34:A2:7D.
