What is the OUI FC:CC:E4?

FC:CC:E4 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Ascon Ltd.. It covers every address from FC:CC:E4:00:00:00 to FC:CC:E4:FF:FF:FF, or 16,777,216 addresses in total. It is also written FC-CC-E4.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in FC:CC:E4:00:00:00 that is FC:CC:E4 — 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 Ascon Ltd. located?

Ascon Ltd. is listed at 1-15-27 Minato-machi Fukuyama –shi Hiroshima-ken JP 721-0964 in the IEEE OUI registry entry for FC:CC:E4. This is the address the organization registered with the IEEE, which may differ from its current operating address.
