Which company owns MAC address prefix FC:A2:2A?

MAC address prefix FC:A2:2A is registered to PT. Callysta Multi Engineering in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with FC:A2:2A has a network interface built by PT. Callysta Multi Engineering.

What is the OUI FC:A2:2A?

FC:A2:2A is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to PT. Callysta Multi Engineering. It covers every address from FC:A2:2A:00:00:00 to FC:A2:2A:FF:FF:FF, or 16,777,216 addresses in total. It is also written FC-A2-2A.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in FC:A2:2A:00:00:00 that is FC:A2:2A — 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 PT. Callysta Multi Engineering located?

PT. Callysta Multi Engineering is listed at Jl. Taman Cibeunying No. 2 Bandung Jawa Barat ID 40114 in the IEEE OUI registry entry for FC:A2:2A. This is the address the organization registered with the IEEE, which may differ from its current operating address.
