So, what is an internet domain? The simplest way to explain the pakistan phone number data of domain is: if your website is a house, the domain is your address, the web address that users type into the URL bar of their browser to access your website.
what is an internet domain
Some examples of internet domains are:
creativemotions.it
Google.com
Facebook.com
Wikipedia.org
Yahoo.com
Instagram.com
For a more technical definition of internet domain: the internet is a giant network of computers connected by a network of cables. Each computer is assigned a unique IP address that allows the computers to communicate with each other. The IP address is a series of numbers used to identify each particular computer. A typical IP address looks like this:
192.168.1.1
An IP address is hard to remember, so website domains were invented to solve this problem. Instead of having to type in a hard-to-remember string of random numbers, users simply type in a website domain, such as PizzaDelivery.com, to visit a website.
Now that you know what website domains are, let’s talk about how they work.
When a user types an Internet domain name into the address bar of an Internet browser, they send a request to the Domain Name System (DNS) , which is a global network of servers. When these servers receive your request, they look up the nameservers associated with the website domain and forward the request to those nameservers .
Your website hosting provider manages your Nameservers. So if your website is hosted on a Siteground web space , it will forward the request to the computer where your website files are stored. This computer is called a web server. The web server then collects the requested website and sends it back to the browser so that the user can view it.

Internet domains can be of different levels. Let's see what they are and what they are used for.
Third level web domains
A third-level domain, also known as a subdomain, is the first part of a domain (from left to right) that comes before the dot.
Example: mail .creativemotions.it
This is a standard part for website domains, called a subdomain . However, this is optional, because you do not need to enter www before a domain name in a browser to access it, it can simply be creativemotions.it without www.
Second level web domains
The second part is the second-level domain, which is the part you are most familiar with.
Example: www. creativemotions.it
This is the very name of your domain that you register for and is the most customizable part.
Top-level Internet domains
Finally, after the dot, there is the top-level domain also known as TLD (Top Level Domain) , it is that part that we commonly call the extension.
Example: www.creativemotions . it
The extension can be .com, .biz, .net, .org, .it, as well as many other variations. But .com is the most popular and well-known.
