Which company owns MAC address prefix 08:1F:3F?

MAC address prefix 08:1F:3F is registered to WondaLink Inc. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 08:1F:3F has a network interface built by WondaLink Inc..

What is the OUI 08:1F:3F?

08:1F:3F is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to WondaLink Inc.. It covers every address from 08:1F:3F:00:00:00 to 08:1F:3F:FF:FF:FF, or 16,777,216 addresses in total. It is also written 08-1F-3F.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 08:1F:3F:00:00:00 that is 08:1F:3F — 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 WondaLink Inc. located?

WondaLink Inc. is listed at 2F, No. 23, R&D Road 2 Hsinchu TW 300 in the IEEE OUI registry entry for 08:1F:3F. This is the address the organization registered with the IEEE, which may differ from its current operating address.
