Which company owns MAC address prefix 68:89:75?

MAC address prefix 68:89:75 is registered to nuoxc in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 68:89:75 has a network interface built by nuoxc.

What is the OUI 68:89:75?

68:89:75 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to nuoxc. It covers every address from 68:89:75:00:00:00 to 68:89:75:FF:FF:FF, or 16,777,216 addresses in total. It is also written 68-89-75.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 68:89:75:00:00:00 that is 68:89:75 — 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 nuoxc located?

nuoxc is listed at 龙岗区横岗街道西坑社区西坑梧岗路9号2栋深圳市广东省 CN 518173 in the IEEE OUI registry entry for 68:89:75. This is the address the organization registered with the IEEE, which may differ from its current operating address.
