what is the email domain name?

In a broad range, an email domain name is considered the address of the server. For example, if your email address is test@Gmail.Com then here domain name is Gmail.

Gmail and Yahoo are the public email domain and indicate Gmail and Yahoo servers respectively but when we purchase our domain like mywebsite.com then mywebsite.com is our personal email domain and will have a dedicated server for this domain name.

Check whether your domain exists or not.

This can vary by the nature of your purchase if you purchased a shared domain then your IP address will be shared but the domain name will be unique, this often comes with the shared hosting plan.

what is this email domain used for?

If there were no email domain systems all the websites would be open with the help of IP addresses like 127.0.0.1 and whenever we wished to open a website then we had to enter the IP address of the site.

This would be possible if there were only 4-5 websites in the world but this is not the reality. In reality, there are more than billions of websites across the world and these numbers are increasing.

It is almost impossible to remember the IP addresses of many websites, so by considering this problem the introduction of domain names came into the picture.

Each website is given a suitable name of its own choice by the DNS.

DNS is known as a domain name system or domain name server this is a server that stores all the website domain names like Gmail and Yahoo.

If any email domain is not registered in the DNS then it is an Illegal domain or disposable domain.

You will see these email domains appended with an extension like .com is known as a domain extension.

What are these email domain extensions?

The domain extension was introduced to represent or show the brand or nature of the website or corresponding company. it makes a website more specific and helps users select the websites correctly.

Nowadays many new extensions are introduced each day like .shoe, .mobile, .fruit, .apple. this is because of more and more demands specifications of products in today’s market.

You can see the hierarchy of a few top-level domains below.

The diagram above shows the hierarchy of DNS. The root is at the top and then .com, .net, .org, .gov, and .mil are considered as generic top-level domains(gTLD).

.COM – For any Commercial purpose, like www.a5theory.com.
.ORG – For different Organizations, like http://www.humanhealth.org.
.NET – For Network solutions, like http://www.besthistory.net
And like this .gov is for the government and .mil for the army(military) section so we have a broad classification of the domain name.

What are the benefits of this email domain name?

It is easy to remember the website name with the help of an email domain name instead of an IP address.

we can also restrict unauthenticated users from entering our portal or website by checking whether their domain exists or not.

Who is managing these DNS servers or email domains?

There are a few classifications of DNS servers, broadly classified into two classes DNS root server and secondary DNS server.

The DNS root server is maintained by a few organizations across different countries and further, this secondary DNS server is maintained by Govt. ISP and private companies across the world.
