![]() You can scan multiple hosts by appending the last part of your IP address.įor example, here, I have searched for: 192.168.1.8, 192.168.1.9, and 192.168.1.10 by appending the last octet: nmap 192.168.1.8,9,10 3. Now, typing each one manually is not the way I and most of you would prefer.Īnd in that case, you can specify the range of IP addresses.įor example, here, I scanned for IP addresses from 192.168.1.8 to 192.168.1.10: nmap 192.168.1.8-10 Scan multiple hosts by appending the ending octet So let's say I want to scan 3 IP addresses. )with the * symbol: nmap 192.168.1.* Scan multiple hosts by specifying the IP range To use the * wildcard, type the IP address, and replace your last octet (the last part of your IP after the. If you have to scan multiple hosts and the list is long enough to make you tired while typing, you can use the wildcard. So basically, if you have to scan 2-3 hosts, this is the easiest method in my opinion where you simply append the IP/domain one by one.įor example, here, I have scanned 3 IP addresses at once: nmap 192.168.1.9 192.168.1.8 192.168.1.10 Use a wildcard to scan the entire subnet Scan multiple hosts by appending domains or IP addresses So let's start with appending the multiple domains/IP addresses. You can also append the different endings of IP addresses rather than typing the entire IP.Using wildcards to search the entire subnet at once.Appending multiple domains or IP addresses to the nmap command.So there are several ways to scan multiple hosts: You may have to scan multiple hosts and nmap offers various ways to scan multiple hosts at the same time for an extensive search. ![]() To search for open ports, all you have to do is append the domain name or the IP address to the nmap command: nmap Targetīut if you are in hurry and want to finish the scan as soon as possible, you can use the -F flag: nmap -F target 2. To install nmap on Ubuntu/Debian base: sudo apt install nmapįor RHEL/Fedora base: sudo dnf install nmapįor Arch-based distros: sudo pacman -S nmap ![]() To know whether you have it installed or not, verify the installed version: nmap -vĪnd if it shows an error, you can refer to the given command. While you would find the nmap package pre-installed on most of the Linux distros, you might not have it pre-installed. So if you try to access a device with the ip 192.168.1.55 try connecting to it by typing 192.168.1.55:8080 in the address bar of your browser.I will be using as a target provided by nmap itself for most of the examples. ![]() Sometimes the remote management surface must be accessed using a special port and most of the time this is the alternative port for webservers 8080.

You can also limit the scan to a rango of ips e.g. after this info you maybe have to specify eth2, do this by altering the above command with the option -interface like this In case you get an error (ioctl: No such device) you might have to choose your network device manually, get a list of all devices installed with this command Scan your local network with just one command Open up a terminal window and install arp-scan by typing The latter is a good hint to which ip a device belongs to. If you have admin rights and are ok with installing a small piece of software from the repository, you can make this task even easier and above it even find out more about the active network devices on your network, like the mac adress and the manufacturer of the network card. Don't know your network's ip range or also need the mac addresses and have admin rights?
