• Each computer on the Internet is assigned with a unique address, called an IP address. A typical IP address looks like this: 192.168.24.30
• It is very difficult for everyone to keep in mind the IP addresses of all the websites we visit daily. In order to make it simplify and to remember easily, domain names comes into the picture.

• The reason is, Words are easier to remember than strings of numbers.
• When you visit a website, all you need to know is its URL(www.wikitechy.com). Computers remember numbers, and DNS helps us convert the URL into an IP address that the computer can understand.

How DNS works?

• When you type in domain.com into your browser, the browser first needs to get the IP address of www.wikitechy.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.
