Nmap done: 256 IP addresses ( 48 hosts up) scanned in 10.28 seconds Performing this same scan on an Internet-connected server can yield a lot of interesting results. This type of IP scanner feature is also called 'ping sweep' or 'ping scan'. Nmap done: 256 IP addresses ( 5 hosts up) scanned in 8.50 secondsĪs you can see, no port scanning has taken place-instead we used Nmap to ping hosts and get a response from each one of them. MAC Address: 70: 77: 81: 76: 9A:EF (Hon Hai Precision Ind.) Here, we're going to skip all port scans, using an option called 'skip port scan': nmap -sP 192.168.1.0/ 24 So let's use some Nmap commands and begin the process of discovering all the servers behind the network. What many people don't realize is that Nmap is the perfect tool for a network IP audit. We've written about Nmap before, back when we explored the best port scanners and showed how easy it is to scan any host when you're seeking critical information such as open ports, OS version, and other pertinent details.

Nmap has been and will probably remain our favorite hacking tool for infosec research tasks, and that includes IP scanning as well. We can't put any other tool in the number 1 spot. Let's take a look at the top IP scanner tools used by system administrators, network engineers and penetration testers.
