Which company owns MAC address prefix 00:10:BD?

MAC address prefix 00:10:BD is registered to THE TELECOMMUNICATION TECHNOLOGY COMMITTEE (TTC) in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 00:10:BD has a network interface built by THE TELECOMMUNICATION TECHNOLOGY COMMITTEE (TTC).

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 00:10:BD:00:00:00 that is 00:10:BD — 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.
