Which company owns MAC address prefix F8:8E:85?

MAC address prefix F8:8E:85 is registered to Comtrend Corporation in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with F8:8E:85 has a network interface built by Comtrend Corporation.

What is the OUI F8:8E:85?

F8:8E:85 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Comtrend Corporation. It covers every address from F8:8E:85:00:00:00 to F8:8E:85:FF:FF:FF, or 16,777,216 addresses in total. It is also written F8-8E-85.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in F8:8E:85:00:00:00 that is F8:8E:85 — 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 Comtrend Corporation located?

Comtrend Corporation is listed at 3F-1, 10 Lane 609, Chongxin Road, Section 5, New Taipei City, Taiwan TW 24159 in the IEEE OUI registry entry for F8:8E:85. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does Comtrend Corporation own?

Comtrend Corporation holds 10 OUI prefixes in the IEEE registry, of which F8:8E:85 is one. A device made by Comtrend Corporation could carry a MAC address from any of them.
