Nmap - Determining if the Host is Up

Hello! Are you there? I know your door is locked but i can tell if you are hiding. :)

Some websites disable ICMP so that when people try to Ping the website or the IP address of the website, it will respond with 'Request Timed Out'.

Nmap has the capability to find out whether the host is up despite not being able to ping. 

Open terminal and type #nmap -sn <IP>

As you can see, nmap shows the reply as '1 host up'. :)
