Which company owns MAC address prefix 68:36:B5?

MAC address prefix 68:36:B5 is registered to DriveScale, Inc. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 68:36:B5 has a network interface built by DriveScale, Inc..

What is the OUI 68:36:B5?

68:36:B5 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to DriveScale, Inc.. It covers every address from 68:36:B5:00:00:00 to 68:36:B5:FF:FF:FF, or 16,777,216 addresses in total. It is also written 68-36-B5.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 68:36:B5:00:00:00 that is 68:36:B5 — 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 DriveScale, Inc. located?

DriveScale, Inc. is listed at 530 Lakeside Dr. #190 Sunnyvale CALIFORNIA US 94085 in the IEEE OUI registry entry for 68:36:B5. This is the address the organization registered with the IEEE, which may differ from its current operating address.
