Which company owns MAC address prefix 50:18:4C?

MAC address prefix 50:18:4C is registered to Platina Systems Inc. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 50:18:4C has a network interface built by Platina Systems Inc..

What is the OUI 50:18:4C?

50:18:4C is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Platina Systems Inc.. It covers every address from 50:18:4C:00:00:00 to 50:18:4C:FF:FF:FF, or 16,777,216 addresses in total. It is also written 50-18-4C.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 50:18:4C:00:00:00 that is 50:18:4C — 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 Platina Systems Inc. located?

Platina Systems Inc. is listed at 3180 De La Cruz Blvd. Ste# 110 Santa Clara CA US 95054 in the IEEE OUI registry entry for 50:18:4C. This is the address the organization registered with the IEEE, which may differ from its current operating address.
