Nmap supports an interesting scanning technique named IP protocol ping scan. It attempts to determine if a host is online by sending packets using IP packets with different protocols.
The following recipe describes how to perform IP protocol ping scans.
Open your terminal and enter the following command:
# nmap -sn -PO <target>
If the host responded to any of the requests, you should see something like the following:
# nmap -sn -PO scanme.nmap.org
Nmap scan report for scanme.nmap.org (45.33.32.156)
Host is up (0.18s latency).
Other addresses for scanme.nmap.org (not scanned):
2600:3c01::f03c:91ff:fe18:bb2f
Nmap done: 1 IP address (1 host up) scanned in 0.40 seconds
