Which company owns MAC address prefix 50:F2:61?

MAC address prefix 50:F2:61 is registered to Photon Sail Technologies in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 50:F2:61 has a network interface built by Photon Sail Technologies.

What is the OUI 50:F2:61?

50:F2:61 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Photon Sail Technologies. It covers every address from 50:F2:61:00:00:00 to 50:F2:61:FF:FF:FF, or 16,777,216 addresses in total. It is also written 50-F2-61.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 50:F2:61:00:00:00 that is 50:F2:61 — 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 Photon Sail Technologies located?

Photon Sail Technologies is listed at 8 Robinson Road, ASO Building Singapore SG 048544 in the IEEE OUI registry entry for 50:F2:61. This is the address the organization registered with the IEEE, which may differ from its current operating address.
