Which company owns MAC address prefix 48:22:18?

MAC address prefix 48:22:18 is registered to Shenzhen Yipingfang Network Technology Co., Ltd. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 48:22:18 has a network interface built by Shenzhen Yipingfang Network Technology Co., Ltd..

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 48:22:18:00:00:00 that is 48:22:18 — 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.

How many MAC prefixes does Shenzhen Yipingfang Network Technology Co., Ltd. own?

Shenzhen Yipingfang Network Technology Co., Ltd. holds 5 OUI prefixes in the IEEE registry, of which 48:22:18 is one. A device made by Shenzhen Yipingfang Network Technology Co., Ltd. could carry a MAC address from any of them.
