What is a domain name?
A domain name is your website name. A domain name is the address where Internet users can access your website. A domain name is used for finding and identifying computers on the Internet. Computers use IP addresses, which are a series of number. However, it is difficult for humans to remember strings of numbers. Because of this, domain names were developed and used to identify entities on the Internet rather than using IP addresses.
A domain name can be any combination of letters and numbers, and it can be used in combination of the various domain name extensions, such as .com, .net and more.
Ex. https://www.sumitsshevtekar.com/ , .edu, .org, .in
The domain name must be registered before you can use it. Every domain name is unique. No two websites can have the same domain name.
Why you need a Domain Name
On the Internet, your domain name is your unique identity. Any individual, business or organization planning to have an Internet presence should invest in a domain name. Having your own domain name, website and email addresses will give you and your business a more professional look. Another reason for a business to register a domain name is to protect copyrights and trademarks, build creditability, increase brand awareness, and search engine positioning.
Domain Name Server (DNS)
Each computer on the Internet is assigned a unique address, called an IP address. A typical IP address looks like this: 199.121.447.1
It is very difficult to keep in mind the IP addresses of all the websites we visit daily. Words are easier to remember than strings of numbers. This is where domain names come into the picture. When you visit a website, all you need to know is its URL. Computers remember numbers, and DNS helps us convert the URL into an IP address that the computer can understand.
When you type in www.sumitsshevtekar.com into your browser, the browser first needs to get the IP address of www.sumitsshevtekar.com. The browser contacts a DNS server to query the location of the server where the webpages are stored. Think of it as a directory service of IP address.
