What is the OUI 30:C6:95?

30:C6:95 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Overview Corporation. It covers every address from 30:C6:95:00:00:00 to 30:C6:95:FF:FF:FF, or 16,777,216 addresses in total. It is also written 30-C6-95.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 30:C6:95:00:00:00 that is 30:C6:95 — 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 Overview Corporation located?

Overview Corporation is listed at 1700 Montgomery St San Francisco CA US 94111 in the IEEE OUI registry entry for 30:C6:95. This is the address the organization registered with the IEEE, which may differ from its current operating address.
