Which company owns MAC address prefix 50:0F:C6?

MAC address prefix 50:0F:C6 is registered to solum in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 50:0F:C6 has a network interface built by solum.

What is the OUI 50:0F:C6?

50:0F:C6 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to solum. It covers every address from 50:0F:C6:00:00:00 to 50:0F:C6:FF:FF:FF, or 16,777,216 addresses in total. It is also written 50-0F-C6.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 50:0F:C6:00:00:00 that is 50:0F:C6 — 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 solum located?

solum is listed at 2354, Yonggu-daero, Giheung-gu Yongin-si Gyeonggi-do KR 16921 in the IEEE OUI registry entry for 50:0F:C6. This is the address the organization registered with the IEEE, which may differ from its current operating address.
