What is a Domain Name and how it works?
In simple words, A Domain Name is a virtual address of a website that is used to access the website. A domain or a domain name is the address of a website that functions as a link to the IP address by which anyone can open the website without having knowledge of IP addresses. Every part of the domain name has a specific meaning and provides access to the website on a web browser like Google Chrome and Internet Explorer. Today due to high demand for domains, the engineer invented a new version which is (IPv6) that helps to prevent confusion between domain names and replicate of domains. Not only this, it also increased the number of domains. Today, we will discuss domains and get a complete Introduction to Domain Name.
Domain Name Example: www.example.com
example.com or example.org is a domain name in which .com stands for the first top-level domain(or also known as domain name extension worldwide) and example is the address.
A domain name can be a combination of letters, numbers or hyphen and can be used with numerous combinations of domain name extensions like .org, .gov, .com, .in, etc.
History of Domain Name
When the internet revolution happened in 1960, scientists extended the use of ARPANET (in 1983) and from that time everything changed. After that, the Internet has become an integral part of people’s lives and they started using it every day. Time by time it brings changes in our daily life as technical and social as well. People started building websites and interacting with the users globally. But accessing the website is not that easy at that time. Many people did not have the technical knowledge to understand the website IP address works.
Paul Mockapetris invented the Domain Name or Domain Name System in 1983 at USC’s Information Sciences Institute and introduced domain names to the world. In 1986 the creation of IETF, DNS became one of the original Internet Standards. This helps users to remember a website name more easily unlike before with numeric address (IP address).
Before Domain name, people have to use the IP address to access any website that was such a headache. After the invention of Domain name, the numeric address encapsulated into a simple language which is today known as a domain name.
What is a DNS (Domain Name System)?
Domain Name System is a classified recognition system of domain names and subdomains. All domains are kind of sub-domains of another domain name. We know about TLD (Top Level Domains) and some others which are handled by domain name system.
Some Best Example of TLD:
Many times as per Country code TLDs also have a two-tier system.
Here are the perfect examples of two-tier systems.
How does DNS (Domain Name System) Work?
We already know that a domain name is a virtual address of a website. When anyone enters a domain name into the web browser then it provides access to the entered website. These all things performed under the background that are still hidden by normal people who don’t have technical knowledge.
For example, Let’s assume a person is coming to your home but he does not have the address of your home. Now, You tell the address of your home to the person so he/she can easily reach your house. That’s how domain works in simple language.
