DNS is the abbreviation for “Domain Name System”. It’s a method that allows you to connect to websites by comparing human-readable domain names to their unique identification number of the server that the website is hosted.
Consider it as the DNS service as the Internet’s telephone book. The DNS system lists domain name and their respective identifiers known as IP addresses instead of listing the names of individuals along with their numbers. If a user types in the domain name such as 192168101.win from their mobile, it searches for the IP address and then connects them to the physical address where the site is located.
Domain name systems are responsible to translate domain names to a specific IP address, so that the client initiating it is able to load desired Internet resources. The domain name system operates similar to a phone book that allows users to look up a individual and get their telephone number. DNS servers convert requests for particular domain names into IP addresses determining who has access to the server to the domain’s name into their browser.
How does DNS work?
A process called DNS resolution involves changing the hostname into an IP address compatible with computers (such such as 192.168.1.1). A IP address will be assigned to every device connected to the Internet and it is required to locate the right Internet device, just as the street address used to locate a specific address. If a user wishes to open a web page there must be a translation between what the user type into their browser and the machine-friendly address required to access the example.com page.
To comprehend the mechanism behind DNS resolution, it is important to know the various hardware components that a DNS query has to pass through. The web browser is the primary one it is the DNS search happens “behind the behind the scenes” and does not require any input with the computer of the user, aside from making the first request.
