Which company owns MAC address prefix 70:F1:1C?

MAC address prefix 70:F1:1C is registered to Shenzhen Ogemray Technology Co.,Ltd in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 70:F1:1C has a network interface built by Shenzhen Ogemray Technology Co.,Ltd.

What is the OUI 70:F1:1C?

70:F1:1C is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Shenzhen Ogemray Technology Co.,Ltd. It covers every address from 70:F1:1C:00:00:00 to 70:F1:1C:FF:FF:FF, or 16,777,216 addresses in total. It is also written 70-F1-1C.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 70:F1:1C:00:00:00 that is 70:F1:1C — 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 Shenzhen Ogemray Technology Co.,Ltd located?

Shenzhen Ogemray Technology Co.,Ltd is listed at 4/F,5Bldg,Dongwu Industrial Park, Donghuan 1st Rd, Longhua District. Shenzhen CN 518059 in the IEEE OUI registry entry for 70:F1:1C. This is the address the organization registered with the IEEE, which may differ from its current operating address.
