Which company owns MAC address prefix 74:95:52?

MAC address prefix 74:95:52 is registered to Xuzhou WIKA Electronics Control Technology Co., Ltd. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 74:95:52 has a network interface built by Xuzhou WIKA Electronics Control Technology Co., Ltd..

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 74:95:52:00:00:00 that is 74:95:52 — 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.
