Which company owns MAC address prefix 08:3F:76?

MAC address prefix 08:3F:76 is registered to Intellian Technologies, Inc. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 08:3F:76 has a network interface built by Intellian Technologies, Inc..

What is the OUI 08:3F:76?

08:3F:76 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Intellian Technologies, Inc.. It covers every address from 08:3F:76:00:00:00 to 08:3F:76:FF:FF:FF, or 16,777,216 addresses in total. It is also written 08-3F-76.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 08:3F:76:00:00:00 that is 08:3F:76 — 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 Intellian Technologies, Inc. located?

Intellian Technologies, Inc. is listed at 348-5 Chungho-Ri Jinwi-Myeon Gyeonggi-Do KR 451-862 in the IEEE OUI registry entry for 08:3F:76. This is the address the organization registered with the IEEE, which may differ from its current operating address.
