What is a domain name?

A domain name is the name of your website. A domain name is the address where Internet users can access your website. A domain name is used to search and identify computers on the Internet. Computers use IP addresses, which are a series of numbers. However, strings of numbers are difficult to remember. Because of this, domain names were developed and used to identify entities on the Internet rather than using IP addresses.

Domain name is an important part of Internet infrastructure. They provide a human-readable address for any web server available on the Internet. A domain name is one of a string of text that maps to a numeric IP address, which is used to access a website from client software. A domain name is the text that a user types in a browser window to access a particular website. For example, Google's domain name is 'google.com'.

A domain name is the name of your website. A domain name is the address where Internet users can access your website. A domain name is used to search and identify computers on the Internet. Computer use IP addresses, which are a series of numbers. However, strings of numbers are difficult to remember. Because of this, domain names were developed and used to identify entities on the Internet rather than using IP addresses.

 

Now that you know how to define a domain name, let's go a little deeper. Like most great ideas, website domains operate on more than one level. They include both a top-level domain (TLD) and a second-level domain (SLD).

 

The second level to the left of the SLD-dot is the domain, which can be your name, your business, blog, or store name. This is the "identity" of your site. In our case, the second level domain is "namespace".

To the right of the TLD-dot is the top-level domain (or TLD), in which case the TLD is ".com", but you may have also seen TLDs such as .net, or .org, or country identifiers such as .uk.

 

A domain name has a simple structure made up of many parts (it can be just one part, two, three ...), separated by dots and read from right to left:

See the section at the top of your browser window in the URL bar? This is the part that starts with "http: //" in the address bar. The second part of the URL is the domain. In our case, it is belinkus.com.

 

TLDs tell users the general purpose of the service behind the domain name. The most common TLD's (.com, .org, .net) web services are not required to meet any specific criteria, but some TLD's implement strict policies so it is clear that they are intended.

 

for example:

 

The most popular TLDs to choose from with basically intended objectives are:

  • .com - All Business Objectives
  • .org - Organization (often non-profit)
  • .net - Network Projects (whatever that means)
  • .edu - educational institute
  • .gov - US Government
  • .biz - Everything Business
  • .info – universal

 

Alternatively, there are also hundreds of local / regional TLDs, such as:

  • .uk - for UK
  • .ca - Canada
  • .pl - Poland
  • .it - ​​Italy

e.t.c.

The domain name must be registered before use. Each domain name is unique. No two websites can have the same domain name. If someone types in www.belinkus.com, it will go to your website and not to anyone else.

The price of a domain name typically runs between $ 15-25 per year.

How do domain names work?

 When you type a domain name in your browser's address bar, your browser searches the website with the corresponding IP address. This is the work of the Domain Name System (DNS). It only maps the domain name (which is very easy for people to remember) to an address that the browser understands.

The DNS system works like this:

Trying to get your browser http://blog.example.com/index.html

First it asks for the primary DNS server that administers the .com domain.

It then asks the .com administrator who administers the example subdomain.

This example then asks the subdomain who administers the subdomain blog.

Finally it asks the subdomain administrator for the blog resource index.html.

This all happens very quickly and automatically. In addition, the web browser remembers this information, so it does not go through the entire process every time.

Exemple -

Your home - your actual home - may fail through its geographic coordinates. For example, some people live at 38.7977 ° N, 55.0365 ° W. But it is difficult to remember that address, so we use 27 Main Zone India instead.

We use that simplified street address so that the location can be understood more quickly and not spend time locating physical coordinates.

This is somewhat similar with domain names. Under the hood, domain names point to specific IP addresses: actual numeric addresses of locations on the web. Therefore, whenever someone tries to visit a given website, their web browser takes the domain name and converts it into a full web address.

 In Other words 

When a domain name is entered into your web browser, a request is sent to the global network of servers that make up the Domain Name System (DNS), which is like an Internet phonebook.

The server then searches the domain-related name servers and forwards the request to the name servers. Name servers are large computers, managed by hosting companies. Hosting Company Webserver

Forwards the request to where your site is stored. The web server receives the requested web page or information and forwards it to the browser.

The Internet Corporation for Assigned Names and Numbers (ICANN) authorizes companies called domain name registrars to sell domain names. It also allows them to make changes to the domain name registry on your behalf and sell the domain name, transferring their records, renewals, and other registrars. As the owner of a domain name, you must renew your domain registration before it expires.

 

 

What is the purpose of the domain?

If you own a business, maybe someone at some point tells you; You should register a domain name. This is because if you have a website, you need a domain name. There are several reasons for entering a domain name, such as:

  1. Registering your domain name means that no one else can use it.
  2. Having a domain name gives your website a professional appearance.
  3. If you register a domain name, you can customize your email.
  4. You know the old saying; If you are not online, you are not present.
