What is the OUI 50:D2:13?

50:D2:13 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to CviLux Corporation. It covers every address from 50:D2:13:00:00:00 to 50:D2:13:FF:FF:FF, or 16,777,216 addresses in total. It is also written 50-D2-13.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 50:D2:13:00:00:00 that is 50:D2:13 — 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 CviLux Corporation located?

CviLux Corporation is listed at 9F,No.9,Lane 3,Sec.1,Chung-Cheng East Road, Tamshui New Taipei City TW 25147 in the IEEE OUI registry entry for 50:D2:13. This is the address the organization registered with the IEEE, which may differ from its current operating address.
