Which company owns MAC address prefix 2C:66:AD?

MAC address prefix 2C:66:AD is registered to NimbleTech Digital Inc. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 2C:66:AD has a network interface built by NimbleTech Digital Inc..

What is the OUI 2C:66:AD?

2C:66:AD is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to NimbleTech Digital Inc.. It covers every address from 2C:66:AD:00:00:00 to 2C:66:AD:FF:FF:FF, or 16,777,216 addresses in total. It is also written 2C-66-AD.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 2C:66:AD:00:00:00 that is 2C:66:AD — 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 NimbleTech Digital Inc. located?

NimbleTech Digital Inc. is listed at 13 F.-9, No. 738, Zhongzheng Rd., Zhonghe Dist., New Taipei City 235603, Taiwan (R.O.C.) New Taipei City TW 235603 in the IEEE OUI registry entry for 2C:66:AD. This is the address the organization registered with the IEEE, which may differ from its current operating address.
