John works as a professional Ethical Hacker. He is assigned a project to test the security of connected to the server or not. Which of the following will he use to ping these computers?

The PING command tests connectivity to a single specified host and cannot efficiently probe an entire range of IP addresses to discover multiple live hosts.

TRACEROUTE maps the network path and hop-by-hop routing between the source and a single destination; it does not test multiple hosts for connectivity.

Ping sweeping is a reconnaissance technique that automates the process of sending ICMP echo request packets to multiple IP addresses across a subnet or range. It allows an ethical hacker to quickly map which hosts are online and reachable without manually pinging each address one at a time. Tools such as Nmap and fping are commonly used to perform ping sweeps during the network discovery phase.

NETSTAT displays current network connections, routing tables, and interface statistics on the local machine and does not send probes to discover remote hosts.
