Which company owns MAC address prefix F8:6C:E1?

MAC address prefix F8:6C:E1 is registered to Taicang T&W Electronics in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with F8:6C:E1 has a network interface built by Taicang T&W Electronics.

What is the OUI F8:6C:E1?

F8:6C:E1 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Taicang T&W Electronics. It covers every address from F8:6C:E1:00:00:00 to F8:6C:E1:FF:FF:FF, or 16,777,216 addresses in total. It is also written F8-6C-E1.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in F8:6C:E1:00:00:00 that is F8:6C:E1 — 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 Taicang T&W Electronics located?

Taicang T&W Electronics is listed at 89# Jiang Nan RD Suzhou Jiangsu CN 215412 in the IEEE OUI registry entry for F8:6C:E1. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does Taicang T&W Electronics own?

Taicang T&W Electronics holds 45 OUI prefixes in the IEEE registry, of which F8:6C:E1 is one. A device made by Taicang T&W Electronics could carry a MAC address from any of them.
