The Domain Name System (DNS) is both a very interesting and also very important element of the global Internet network. It is hard to imagine what the world would look like if it was not developed! If this is the first time you have heard about the Domain Name System, don’t worry! So, let’s explain all you need to know about it!
Domain Name System (DNS) – Definition
The Domain Name System, also known for short DNS, is a decentralized hierarchical infrastructure. It contains a database at its core with all of the existing domain names and the IP addresses associated with them.
That way, it makes the Internet simple and easy to use for regular users nowadays.
At the moment when a user desires to see a precise website, it writes its domain name in the browser. That action triggers a process (DNS resolution) for finding the corresponding IP address of that domain name. Numerical identification is needed because machines are not able to communicate with words. Therefore the domain name is translated to IP address. Once that address is found, the browser is able to connect and load the website.
If we look back to the days when the Domain Name System (DNS) was not developed yet, it was not so easy to reach your favorite website. Then you would have to remember and type the long and difficult IP address rather than writing the simple and easy domain name. An absolute memory challenge! Thankfully the Domain Name System (DNS) allowed regular users to operate with the domain names and gave the ability to machines to connect with their preferred language (IP addresses).
Purpose of Domain Name System (DNS)
The existence of the Domain Name System is crucial! It serves several essential purposes, which allow users to have an incredible and easy experience on the Internet. They are the following:
- It resolves domain names.
- It allows quick and easy searches on the Internet.
- It implements DNS caching for even faster responses.
- You can complete a Load balancing technique.
- You can use it for verifying services, servers, emails, and more
- It routes messages, thanks to email servers.
- It performs service routing.
If you are wondering how you can take advantage of all of the opportunities of the Domain Name System (DNS), you should get familiar with the different DNS services.
