An IP protocol scan is called a scan type that lets you determine which protocols are supported by the machines to which the scan is addressed. The protocols in question are those that can rely on IP protocol, so also protocols like ip over ip.

Scanning is to send a packet with a certain protocol type to the target machine. If the protocol is not active, the target host will respond with a unreachable (type 3, code 2) unmodified ICMP package. If the protocol is active instead, you will not receive any response.
