Which company owns MAC address prefix 1C:22:85?

MAC address prefix 1C:22:85 is registered to Serrature Meroni SpA in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 1C:22:85 has a network interface built by Serrature Meroni SpA.

What is the OUI 1C:22:85?

1C:22:85 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Serrature Meroni SpA. It covers every address from 1C:22:85:00:00:00 to 1C:22:85:FF:FF:FF, or 16,777,216 addresses in total. It is also written 1C-22-85.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 1C:22:85:00:00:00 that is 1C:22:85 — 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 Serrature Meroni SpA located?

Serrature Meroni SpA is listed at Via Valsorda INVERIGO CO IT 22044 in the IEEE OUI registry entry for 1C:22:85. This is the address the organization registered with the IEEE, which may differ from its current operating address.
