What is DNS
15411611249 or “Process”, which of these can you remember better? Most people would say “Process” because it is easier to remember a word rather than numbers. This is what Domain Name System (DNS) is for.
In the past, if someone would like to go to a website, they will have to remember a string of number known as IP address. However, with the DNS it allows people to use words instead of numbers to navigate on the internet.
How does it work?
So how does your browser look for the website that you are searching for? For the explanation, we will be using “quape.com” as an example.
When you look up “quape.com”, a server known as the recursive resolver will try to find if the website’s information is already stored in a cache. If not, it will send a request to a root nameserver that is nearest to you. Your Internet Service Provider (ISP) is usually responsible for the recursive resolver.
The root nameserver are responsible for all the information on the top-level domain such as the location. Top-level domain are the words that can be found at the end of the domain name like .com, .net. After connecting to the nearest root nameserver, it will then go to a TLD nameserver.
The TLD nameserver will then look for information on “quape” and send a request to the authoritative nameserver.
The authoritative nameserver is usually the DNS registrar and will provide the IP address which the browser will use to load the website. This entire process happens in a matter of milliseconds.
