Get IP from Mac Address in Linux

When setting up a home network, one often wonders how to identify the various devices connected to it. In this article, we will explore how to get an IP address from a MAC address using Linux.

Firstly, it's essential to understand that your router can only handle a maximum of 254 devices at any given time. However, in most cases, you'll find yourself with 3-10 devices connected to your local network. To identify all the devices connected, use the `nmap` command followed by the IP address of your gateway (router) and the subnet mask.

For instance, if your IP address is `192.168.0.104` and your subnet mask is `255.255.255.0`, you can run the following command:

```

sudo nmap -sn 192.168.0.1/24

```

This will display a list of all devices connected to your local network, including their IP addresses.

To get started, find your own IP address by typing `ip addr show` or `ifconfig`. This will give you an idea of what your local IP address looks like and the subnet mask. In most cases, this information can be found in the first section of the output.

Once you have this information in hand, you can use it to get the MAC addresses of other devices on the same network as you. To do this, run the following command:

```

nmap -sP 192.168.0.1/24

```

This will show you a list of all devices connected to your local network, including their IP and MAC addresses.

In conclusion, using Linux, you can easily get an IP address from a MAC address by identifying the devices on your local network. By following these simple steps, you'll be able to keep track of all the devices connected to your network.
