Which company owns MAC address prefix C0:74:15?

MAC address prefix C0:74:15 is registered to IntelPro Inc. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with C0:74:15 has a network interface built by IntelPro Inc..

What is the OUI C0:74:15?

C0:74:15 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to IntelPro Inc.. It covers every address from C0:74:15:00:00:00 to C0:74:15:FF:FF:FF, or 16,777,216 addresses in total. It is also written C0-74-15.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in C0:74:15:00:00:00 that is C0:74:15 — 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 IntelPro Inc. located?

IntelPro Inc. is listed at 19F.-1, No. 168, Sec. 2, Fuxing 3rd Rd., Zhubei City, Hsinchu County TW 302052 in the IEEE OUI registry entry for C0:74:15. This is the address the organization registered with the IEEE, which may differ from its current operating address.
