Which company owns MAC address prefix 70:D9:83?

MAC address prefix 70:D9:83 is registered to Shanghai JINXVM Microelectronics Co.,Ltd. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 70:D9:83 has a network interface built by Shanghai JINXVM Microelectronics Co.,Ltd..

What is the OUI 70:D9:83?

70:D9:83 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Shanghai JINXVM Microelectronics Co.,Ltd.. It covers every address from 70:D9:83:00:00:00 to 70:D9:83:FF:FF:FF, or 16,777,216 addresses in total. It is also written 70-D9-83.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 70:D9:83:00:00:00 that is 70:D9:83 — 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 Shanghai JINXVM Microelectronics Co.,Ltd. located?
