What is the OUI DC:70:35?

DC:70:35 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Shengzhen Gongjin Electronics. It covers every address from DC:70:35:00:00:00 to DC:70:35:FF:FF:FF, or 16,777,216 addresses in total. It is also written DC-70-35.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in DC:70:35:00:00:00 that is DC:70:35 — 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 Shengzhen Gongjin Electronics located?

Shengzhen Gongjin Electronics is listed at No. 2 Danzi North Road, Kengzi Street, Pingshan District Shenzhen Guangdong CN 518122 in the IEEE OUI registry entry for DC:70:35. This is the address the organization registered with the IEEE, which may differ from its current operating address.
