What are Domain Names?
In one line, the domain name can be defined as the name of a website. It is a general and human-understandable way to locate a website on the Internet. Every website which is live on the Inter has some particular address and usually, IPv4 Addresses are used to find out the exact server location of a website. The domain names simply point out to these IPv4 addresses and therefore whenever we type a website domain name in the web browser, it simply redirects us to the established connection with the server of the website. IP addresses are numerical and something, which is difficult to memorize and easily forgettable. Domain names are simpler, usually the combination of some words and phrases, which human beings can easily understand and memorize.
A few examples of domain names are wtmatter.com, google.com, facebook.com, twitter.com, media.net, labnol.org, etc. Domain names can be registered by Domain Name Registrars such as GoDaddy.
ICANN (Internet Corporation for Assigned Names and Numbers) is the organization behind domain names and it also authorizes the registers to sell domain names. Domain Names registrations are commonly priced from $1 to $20 per year. These companies may charge you an exceptionally high price for some special domain names, known as Premium Domain Names. These are the domains with some value as if it contains some prominent keyword or brand name.
If you want to start your own blog, then you also need to get a domain for your blog and as well as web-hosting service to host your blog. A lot of free blogging platforms like Blogger allow you to create blogs without requiring you to buy your own domain, rather you can create a blog with them using their subdomain. Subdomains are simply part of your main domain name. For example, en.wikipedia.org, this is the subdomain of the main domain, wikipedia.org.
The Working of Domain Names
As mentioned, domain names are the medium to help humans to reach the actual server address of a website. Domain names simply translate into the original address of the webserver. But how does this translation process is being done?
There are numerous DNS servers present across the world which keeps the list of the website domain names and their corresponding IP addresses. Whenever you type the domain name of some website in the URL bar of your browser, it gets connected to the nearest DNS server and then lookup for the corresponding IP address for the requested domain name. Once found, it simply redirects the browser client to the actual address of the website server. And can you imagine all of this happens in just a few milliseconds? This process is known as DNS propagation. Usually, DNS takes around 10 to 20 milliseconds.
