Linux Tutorial: How to Find Hostname From IP Address in Linux

Are you a Linux user who wants to learn the command line to find a hostname from an IP address? If so, then this Linux tutorial is for you! In this article, we’ll explain how to use the command line to find a hostname from an IP address in Linux. With this tutorial, you’ll be able to gain a better understanding of how the Linux command line works and how to use it to find a hostname from an IP address.

If you’ve ever been curious about the command line in Linux, then this is the perfect starting point. We’ll explain the basics of how to use the command line and then show you how to use the command line to find a hostname from an IP address. So, if you’re ready to learn, then let’s get started!

The first thing you need to do is open a terminal window. To do this, simply press the Ctrl + Alt + T keys on your keyboard. Once the terminal window is open, you can then type in the command “hostname” followed by the IP address. This command will return the hostname associated with that IP address.

For example, if you wanted to find the hostname associated with the IP address 192.168.1.1, then you would type in the command “hostname 192.168.1.1” and press Enter. The terminal window will then display the hostname associated with that IP address.

Now that you know how to use the command line to find a hostname from an IP address in Linux, you can use this knowledge for all sorts of tasks. From troubleshooting network problems to configuring a web server, the command line can be a powerful tool for Linux users. So, if you’re looking to get the most out of your Linux system, then this tutorial is a great place to start.

We hope this Linux tutorial has helped you learn how to use the command line to find a hostname from an IP address in Linux. With this new knowledge, you can start to explore the possibilities of the Linux command line. So, don’t wait any longer – dive in and start learning!

One of the most important things to know about a Linux system is the hostname. Knowing the hostname is essential for performing different administrative tasks such as connecting to a specific system, viewing system logs, etc. A hostname is a unique name that is used to identify a system on a network. It is usually the first part of a fully qualified domain name (FQDN). In this tutorial, we will learn how to find the hostname of a Linux system from its IP address using the terminal.

Prerequisites

Before you begin this guide, you should have a non-root user account with sudo privileges set up on your system. You can learn how to do this by following our Ubuntu 16.04 initial server setup guide. You should also have access to the command line/terminal window on your system.

Find Hostname from IP Address in Linux

In order to find the hostname from an IP address in a Linux system, we will use the ‘hostname’ command. This command will display the hostname of the system as well as other information such as the IP address and the operating system version. To use the hostname command, simply type the following in the terminal:

Code Block

hostname

The output will look something like this:

Code Block

ubuntu-1604-xenial

The first part of the output is the hostname of the system. This is the name that is used to identify the system on the network. In this case, it is ‘ubuntu-1604-xenial’. You can also use the ‘hostname -i’ command to get the IP address of the system. The output will look something like this:

Code Block

192.168.1.20

Now that we have the IP address of the system, we can use the ‘host’ command to find the hostname from the IP address. This command will query the DNS server for the hostname associated with the given IP address. To use the host command, simply type the following in the terminal:

Code Block

host 192.168.1.20

The output will look something like this:

Code Block

ubuntu-1604-xenial.example.com has address 192.168.1.20

The output shows that the hostname for the given IP address is ‘ubuntu-1604-xenial.example.com’. This is the same as the hostname that we got from the ‘hostname’ command.

In this tutorial, we have learned how to find the hostname of a Linux system from its IP address using the terminal. We have also learned how to use the ‘host’ command to find the hostname from an IP address. Knowing the hostname and IP address of a system is essential for performing various administrative tasks such as connecting to a specific system, viewing system logs, etc. We hope you have found this tutorial useful.
