Which company owns MAC address prefix CC:4A:E1?

MAC address prefix CC:4A:E1 is registered to fourtec -Fourier Technologies in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with CC:4A:E1 has a network interface built by fourtec -Fourier Technologies.

What is the OUI CC:4A:E1?

CC:4A:E1 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to fourtec -Fourier Technologies. It covers every address from CC:4A:E1:00:00:00 to CC:4A:E1:FF:FF:FF, or 16,777,216 addresses in total. It is also written CC-4A-E1.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in CC:4A:E1:00:00:00 that is CC:4A:E1 — 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 fourtec -Fourier Technologies located?

fourtec -Fourier Technologies is listed at 16 Hamelacha St. POB 11681 Rosh Ha’ayin IL 48091 in the IEEE OUI registry entry for CC:4A:E1. This is the address the organization registered with the IEEE, which may differ from its current operating address.
