What is hostname?

A hostname is a name called on the network. The term hostname is used for computer name and website name. It helps to distinguish the machines on a local network. Basically, a hostname is an internet address of a website or machine.

A hostname for a computer can be any selectable name DESKTOP-MZ53DV or anything you want.

As we already know that IP address (e.g., 69.171.250.35) is difficult to remember while hostname (facebook.com) is easy to call and remind. Thereby hostname came into existence. In real life, each person has any name for identifying him. Similarly, hostname helps to identify a machine or website by its hostname.

A hostname for a website may be a domain name with a prefix. For example, a hostname for the domain tutoraspire.com is www.tutoraspire.com.com.

Get the hostname of a computer

Sometimes, you require the hostname of your computer system when it connects with a network. The hostname helps the other devices to find your computer on that network. You can easily get the hostname of your computer system by typing a simple command on command prompt (CMD) in the Windows operating system.

Command 1

Open the command prompt (CMD in Windows) and run the above command on it.

Method 1: Using ping command

In this method, we will run a ping command to get the hostname of a website using the IP address. So, copy and run the below command on CMD (Command Prompt) in Windows operating system.

For example,

Example 1

Run the command on CMD to get the hostname for the IP address 8.8.8.8. For your information, this IP address is the IP address of Google.

Method 2: Using nslookup command

This is another method to get the hostname from the IP address. Run the nslookup command with an IP address from which you want to get the hostname. This command works a bit differently from the ping command that is discussed above. See the syntax to run on command prompt (CMD).

Syntax

For example

Example 1

What is IP address?

An IP address refers to the Internet Protocol address. An Internet Protocol address is your hardware address on the network. E.g., Every computer system has an IP address when it is on a network. An IP address is always unique for all devices connected within a network.

The IP address can be different for the same computer device every time when it gets connected with a network. However, the IP address of a website is always the same that can be used to access a website on the web.

You can access a website either using its web address or IP address. Basically, it is difficult to remember the number of IP addresses compared to website names.
