Which company owns MAC address prefix 30:C8:2A?

MAC address prefix 30:C8:2A is registered to WI-BIZ srl in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 30:C8:2A has a network interface built by WI-BIZ srl.

What is the OUI 30:C8:2A?

30:C8:2A is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to WI-BIZ srl. It covers every address from 30:C8:2A:00:00:00 to 30:C8:2A:FF:FF:FF, or 16,777,216 addresses in total. It is also written 30-C8-2A.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 30:C8:2A:00:00:00 that is 30:C8:2A — 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 WI-BIZ srl located?

WI-BIZ srl is listed at Via Carlo Ferrero 10 Cascine Vica Rivoli Torino IT 10098 in the IEEE OUI registry entry for 30:C8:2A. This is the address the organization registered with the IEEE, which may differ from its current operating address.
