What is the OUI 58:23:8C?

58:23:8C is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Vantiva USA LLC. It covers every address from 58:23:8C:00:00:00 to 58:23:8C:FF:FF:FF, or 16,777,216 addresses in total. It is also written 58-23-8C.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 58:23:8C:00:00:00 that is 58:23:8C — 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 Vantiva USA LLC located?

Vantiva USA LLC is listed at 5030 Sugarloaf Parkway Bldg 6 Lawrenceville GA US 30044 in the IEEE OUI registry entry for 58:23:8C. This is the address the organization registered with the IEEE, which may differ from its current operating address.
