What is the OUI 50:BB:9F?

50:BB:9F 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 50:BB:9F:00:00:00 to 50:BB:9F:FF:FF:FF, or 16,777,216 addresses in total. It is also written 50-BB-9F.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 50:BB:9F:00:00:00 that is 50:BB:9F — 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 4855 Peachtree Industrial Blvd, Suite 200 Norcross GA US 30902 in the IEEE OUI registry entry for 50:BB:9F. This is the address the organization registered with the IEEE, which may differ from its current operating address.
