Which company owns MAC address prefix 68:BE:49?

MAC address prefix 68:BE:49 is registered to Nebula Matrix in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 68:BE:49 has a network interface built by Nebula Matrix.

What is the OUI 68:BE:49?

68:BE:49 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Nebula Matrix. It covers every address from 68:BE:49:00:00:00 to 68:BE:49:FF:FF:FF, or 16,777,216 addresses in total. It is also written 68-BE-49.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 68:BE:49:00:00:00 that is 68:BE:49 — 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 Nebula Matrix located?

Nebula Matrix is listed at 24/F Ahoke Aurora Plaza, Zhongmei RD, Longhua Dist. Shenzhen Guangdong CN 518000 in the IEEE OUI registry entry for 68:BE:49. This is the address the organization registered with the IEEE, which may differ from its current operating address.
