Getting Your IP Address and MAC Address in Linux

Are you tired of wondering what devices are connected to your local network? Do you need to find out how many devices are using your internet connection? In this article, we will explore a simple way to get your IP address and the MAC addresses of other devices on the same network.

To start, you'll need to know that with Linux, you can use the Nmap program to scan your local network for connected devices. This program is incredibly useful for running diagnostics on your device and network. To install Nmap on your computer, simply type `sudo apt-get install nmap` in the command line.

Once installed, you'll need to know your gateway (router) IP address. You can find this by checking your router's settings or looking at the documentation that came with it. For example, if your router's IP address is 192.168.0.1, you would use `sudo nmap -sn 192.168.0.1/24` in the command line. The '24' behind the slash represents the correct number of bits for a subnet mask of 255.255.255.0.

Running this command will show you all the devices connected to your local network. You may see between 3-10 devices, depending on how many devices are connected. Each device will have an IP address and MAC address associated with it.

Now that you know what devices are connected to your network, let's talk about finding your own IP address. Your IP address is usually something like 192.168.0.104, and the subnet mask is typically 255.255.255.0. You can find this information by typing `ifconfig` or `ip addr show` in the command line.

Finally, to get a list of all devices on your local network, simply type `nmap -sn 192.168.0.1/24` and press Enter. This will give you a list of all connected devices, along with their IP addresses and MAC addresses.

By following these simple steps, you can easily find the IP address of any device on your local network using Linux. Whether you're trying to troubleshoot connection issues or simply want to know what devices are connected, this process is quick and easy.
