The Domain Name System (DNS) is used to convert IP addresses into readable domains such as w3services.net . Without DNS everyone would have to remember random strings of number to access different websites. Check Amazon EC2 Instance Comparison for pricing.

When you interact with a domain such as google.co.in, the browsing device runs through a series of requests to convert the URL into a machine-readable IP address every time you send emails, view websites or stream content.
The first stage in resolving a domain is to look at the local DNS cache. If your device can’t find the IP address it will start a DNS query with your Internet Service Provider’s recursive DNS servers. These servers have their own caches and are often able to return the required information to the user.
