What is the OUI 00:A0:5C?

00:A0:5C is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to INVENTORY CONVERSION, INC./. It covers every address from 00:A0:5C:00:00:00 to 00:A0:5C:FF:FF:FF, or 16,777,216 addresses in total. It is also written 00-A0-5C.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 00:A0:5C:00:00:00 that is 00:A0:5C — 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 INVENTORY CONVERSION, INC./ located?

INVENTORY CONVERSION, INC./ is listed at NEKOTECH DIVISION HAMPTON NH US 03842 in the IEEE OUI registry entry for 00:A0:5C. This is the address the organization registered with the IEEE, which may differ from its current operating address.
