If you want to list valid connected IPs in your local network, you can do it by logging into your router if you have a password, else you can check connected client IPs command line using either of the following two commands.

  1. See All Devices On Network Cmd
  2. See All Devices On Network Windows
  3. See All Devices On Network Command Prompt

Go to the Connectivity tab, and click the Scan for devices button under your network name. The scan only takes a second and the list you get will identify the device by type i.e., phone, desktop, tablet, the router, any access points, printers, etc., and it will also tell you what OS the device is running. We will use both, command line and GUI, way for finding out what devices are connected to your local network in Linux. The process is very simple and easy to use even for beginners. Using Linux command to find devices on the network Step 1: Install nmap. Nmap is one of the most popular network scanning tool in Linux. Use the following command to install nmap in Ubuntu based Linux distributions. The devices include anything on your network, like Macs, PCs, iPhones, iPads, and routers. It shows both the LAN IP address and MAC address (mine are blacked out in the screenshot to keep them. On many D-Link routers, a list of connected devices is available under Status Wireless. On many Netgear routers, you’ll find the list under “Attached Devices” in the sidebar. On many Linksys routers, you’ll find this option under Status Local Network DHCP Clients Table. To view devices on the network: 1. Launch an Internet browser from a computer or wireless device that is connected to the network. Type or A login screen displays. Enter the router user name and password. The user name is admin.

namp
arp

Let’s see, how you can list connected systems IPs in your netowrk using these commands

List IPs using command namp

Basically this command namp is used to scan networks. It is most widely used as port scanner. You can do many things with this command.

Auditing the security of a device or firewall by identifying the network

Identifying open ports on a target host

Network i maintenance and asset management.

Generating traffic to hosts on a network, response analysis and response time measurement.

Command to see all devices on network

Find and exploit vulnerabilities in a network

Ok, lets come to main thing listing IPs of connected systems in network

nmap -sP 192.168.1.*

Where, you have to specify the IP range or subnet to scan to get the list of connected hosts. Options -sP no port scan based on your version you can also use option -sn.

Warning: Do not performs scans on a network without proper authorization.

List IPs using command arp

Basically arp is the protocol which stands for Address Resolution Protocol. Many linux boxes are loaded with command arp

See All Devices On Network Cmd

Ping your network using a broadcast address i.e. “ping 192.168.2.255” if your IP is 192.168.2.8 or something in same network. After that, perform “arp -a” to determine all the computing devices connected to the network

Note: You can find your broadcast IP in ifconfig output for corresponding network interface

You can use the following command to list connected clients after you ping your broadcast IP,

arp -a

This command will list most of the IPs found but it’s not that much accurate. Some times routers hide machines which are connected via wire to the machines which are connected via wifi network.
