Which company owns MAC address prefix 2C:F7:F1?

MAC address prefix 2C:F7:F1 is registered to Seeed Technology Inc. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 2C:F7:F1 has a network interface built by Seeed Technology Inc..

What is the OUI 2C:F7:F1?

2C:F7:F1 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Seeed Technology Inc.. It covers every address from 2C:F7:F1:00:00:00 to 2C:F7:F1:FF:FF:FF, or 16,777,216 addresses in total. It is also written 2C-F7-F1.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 2C:F7:F1:00:00:00 that is 2C:F7:F1 — 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 Seeed Technology Inc. located?

Seeed Technology Inc. is listed at 5th Floor, 8th Building, Shiling industrial Park, XiLi Town, NanShan dist. Shenzhen ShenZhen GuangDong CN 518055 in the IEEE OUI registry entry for 2C:F7:F1. This is the address the organization registered with the IEEE, which may differ from its current operating address.
