Which company owns MAC address prefix 14:35:B3?

MAC address prefix 14:35:B3 is registered to Future Designs, Inc. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 14:35:B3 has a network interface built by Future Designs, Inc..

What is the OUI 14:35:B3?

14:35:B3 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Future Designs, Inc.. It covers every address from 14:35:B3:00:00:00 to 14:35:B3:FF:FF:FF, or 16,777,216 addresses in total. It is also written 14-35-B3.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 14:35:B3:00:00:00 that is 14:35:B3 — 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 Future Designs, Inc. located?

Future Designs, Inc. is listed at 996 A Cleaner Way SW Huntsville AL US 35805 in the IEEE OUI registry entry for 14:35:B3. This is the address the organization registered with the IEEE, which may differ from its current operating address.
