Which company owns MAC address prefix 30:50:F1?

MAC address prefix 30:50:F1 is registered to Ennoconn Corporation. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 30:50:F1 has a network interface built by Ennoconn Corporation..

What is the OUI 30:50:F1?

30:50:F1 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Ennoconn Corporation.. It covers every address from 30:50:F1:00:00:00 to 30:50:F1:FF:FF:FF, or 16,777,216 addresses in total. It is also written 30-50-F1.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 30:50:F1:00:00:00 that is 30:50:F1 — 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 Ennoconn Corporation. located?

Ennoconn Corporation. is listed at 3-6F,No.10,JiangKang Rd.,Zhonghe Dist.,New Taipei City 23586,Taiwan TaiPei Taiwan TW 23586 in the IEEE OUI registry entry for 30:50:F1. This is the address the organization registered with the IEEE, which may differ from its current operating address.
