Which company owns MAC address prefix AC:3C:8E?

MAC address prefix AC:3C:8E is registered to Flextronics Computing(Suzhou)Co.,Ltd. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with AC:3C:8E has a network interface built by Flextronics Computing(Suzhou)Co.,Ltd..

What is the OUI AC:3C:8E?

AC:3C:8E is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Flextronics Computing(Suzhou)Co.,Ltd.. It covers every address from AC:3C:8E:00:00:00 to AC:3C:8E:FF:FF:FF, or 16,777,216 addresses in total. It is also written AC-3C-8E.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in AC:3C:8E:00:00:00 that is AC:3C:8E — 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 Flextronics Computing(Suzhou)Co.,Ltd. located?

Flextronics Computing(Suzhou)Co.,Ltd. is listed at No.1 GuanPu Road. Guoxiang street , WuZhong District,Suzhou City, Jiangsu Province. Suzhou CN 215124 in the IEEE OUI registry entry for AC:3C:8E. This is the address the organization registered with the IEEE, which may differ from its current operating address.
