While Nmap is commonly used for security audits, many systems and network administrators find it useful for routine tasks such as network inventory, managing service upgrade schedules, and monitoring host or service uptime. Nmap uses raw IP packets in novel ways to determine what hosts are available on the network, what services (application name and version) those hosts are offering, what operating systems (and OS versions) they are running, what type of packet filters/firewalls are in use, and dozens of other characteristics. It was designed to rapidly scan large networks, although it works fine against single hosts. Nmap (вЂњNetwork MapperвЂќ) is an open source tool for network exploration and security auditing. Nmap in action What is Nmap and what is it used for? Let us see some common nmap command examples.

That leads to the net obvious question which is how do you detect hosts on the network that do not respond to ping and ICMP request (as some users intentionally disable ICMP request response on Mac, Windows, or Linux computers), but to do that youвЂ™d likely have to port scan on the network rather than rely on ping. Nmap done: 4096 IP addresses (7 hosts up) scanned in 43.67 secondsД®ssentially how this works is that nmap attempts to ping the host IP range on the network to see if they exist, if they do and respond they are returned in the nmap results, and if they donвЂ™t or do not respond they will not be listed.

Hit Return and wait a moment or two to see the detected hosts on the networkД¬ommand output of nmap may look something like the following, where host IP addresses of found devices and hardware on the network are detected and displayed:.

Enter the following command string, replacing your network IP and range as appropriate:.

Launch the Terminal if you have not done so already.

Ready to list all hosts IP addresses on a network with nmap? ItвЂ™s easy, hereвЂ™s all you need to do: How to Find All Hosts on Network with nmap If you can not use nmap for whatever reason, you may find viewing IP addresses of LAN devices with arp to be useful instead as an alternative solution.
