Which company owns MAC address prefix 50:58:4F?

MAC address prefix 50:58:4F is registered to waytotec,Inc. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 50:58:4F has a network interface built by waytotec,Inc..

What is the OUI 50:58:4F?

50:58:4F is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to waytotec,Inc.. It covers every address from 50:58:4F:00:00:00 to 50:58:4F:FF:FF:FF, or 16,777,216 addresses in total. It is also written 50-58-4F.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 50:58:4F:00:00:00 that is 50:58:4F — 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 waytotec,Inc. located?

waytotec,Inc. is listed at #604-4,B-Dong,Bundang Technopark,148,Yatap-dong,Bundang-gu, Seongnam-si Gyeonggi-do KR 13511 in the IEEE OUI registry entry for 50:58:4F. This is the address the organization registered with the IEEE, which may differ from its current operating address.
