Which company owns MAC address prefix A0:67:BE?

MAC address prefix A0:67:BE is registered to Sicon srl in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with A0:67:BE has a network interface built by Sicon srl.

What is the OUI A0:67:BE?

A0:67:BE is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Sicon srl. It covers every address from A0:67:BE:00:00:00 to A0:67:BE:FF:FF:FF, or 16,777,216 addresses in total. It is also written A0-67-BE.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in A0:67:BE:00:00:00 that is A0:67:BE — 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 Sicon srl located?

Sicon srl is listed at Via Sila 1/3 Isola Vicentina Vicenza IT 36033 in the IEEE OUI registry entry for A0:67:BE. This is the address the organization registered with the IEEE, which may differ from its current operating address.
