Which company owns MAC address prefix 64:55:63?

MAC address prefix 64:55:63 is registered to Q-Free America, Inc. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 64:55:63 has a network interface built by Q-Free America, Inc..

What is the OUI 64:55:63?

64:55:63 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Q-Free America, Inc.. It covers every address from 64:55:63:00:00:00 to 64:55:63:FF:FF:FF, or 16,777,216 addresses in total. It is also written 64-55-63.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 64:55:63:00:00:00 that is 64:55:63 — 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-Free America, Inc. located?

Q-Free America, Inc. is listed at 1420 Kristina Way, Suite #102 Chesapeake VA US 23320 in the IEEE OUI registry entry for 64:55:63. This is the address the organization registered with the IEEE, which may differ from its current operating address.
