Which company owns MAC address prefix 68:3C:7D?

MAC address prefix 68:3C:7D is registered to Magic Intelligence Technology Limited in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 68:3C:7D has a network interface built by Magic Intelligence Technology Limited.

What is the OUI 68:3C:7D?

68:3C:7D is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Magic Intelligence Technology Limited. It covers every address from 68:3C:7D:00:00:00 to 68:3C:7D:FF:FF:FF, or 16,777,216 addresses in total. It is also written 68-3C-7D.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 68:3C:7D:00:00:00 that is 68:3C: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 Magic Intelligence Technology Limited located?

Magic Intelligence Technology Limited is listed at B13/Flat 4,East block,Jinhui Blding.Nanhai Road Nanshan District, Shenzhen guangdong CN 518000 in the IEEE OUI registry entry for 68:3C:7D. This is the address the organization registered with the IEEE, which may differ from its current operating address.
