A ping sweep is the best way to identify which IP addresses belong to active hosts. It sends ICMP Echo Request packets to a range of IP addresses, and if it receives an ICMP Echo Response packet, it knows that the IP address is active and belongs to a live host. This can help to narrow down the scope of the port scan to only active hosts, saving time and resources.
