Which company owns MAC address prefix 10:BD:55?

MAC address prefix 10:BD:55 is registered to Q-Lab Corporation in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 10:BD:55 has a network interface built by Q-Lab Corporation.

What is the OUI 10:BD:55?

10:BD:55 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Q-Lab Corporation. It covers every address from 10:BD:55:00:00:00 to 10:BD:55:FF:FF:FF, or 16,777,216 addresses in total. It is also written 10-BD-55.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 10:BD:55:00:00:00 that is 10:BD:55 — 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 Q-Lab Corporation located?

Q-Lab Corporation is listed at 800 Canterbury Rd Westlake OH US 44145 in the IEEE OUI registry entry for 10:BD:55. This is the address the organization registered with the IEEE, which may differ from its current operating address.
