Which company owns MAC address prefix 50:AD:71?

MAC address prefix 50:AD:71 is registered to Tessolve Semiconductor Private Limited in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 50:AD:71 has a network interface built by Tessolve Semiconductor Private Limited.

What is the OUI 50:AD:71?

50:AD:71 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Tessolve Semiconductor Private Limited. It covers every address from 50:AD:71:00:00:00 to 50:AD:71:FF:FF:FF, or 16,777,216 addresses in total. It is also written 50-AD-71.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 50:AD:71:00:00:00 that is 50:AD:71 — 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 Tessolve Semiconductor Private Limited located?

Tessolve Semiconductor Private Limited is listed at Plot No: 31, P2, Electronic City Phase II, Electronic City Bengaluru Karnataka IN 560100 in the IEEE OUI registry entry for 50:AD:71. This is the address the organization registered with the IEEE, which may differ from its current operating address.
