Sometimes, the problem is related to the default DNS (Domain Name System) used by the ISP. So, let me explain you something about DNS before telling you the method to get a faster internet speed.

What is DNS?

DNS – Domain Name System – is a naming system that is used to convert the domain names into IP addresses. The domain names are usually alphanumeric for us to remember quickly, but in actuality, the Internet works on IP addresses. The DNS server, for a domain name, returns its corresponding IP address when requested by your computer (client).

The DNS has a network of its own i.e. one DNS server can ask other DNS servers about translating a particular domain name to its corresponding IP address till it gets the correct result.

Computers and other devices make use of IP address to route the traffic, and it is very much similar to dialing a phone number. DNS acts as an intelligent operator that helps us bypass the infinite address book of IP addresses. Your DNS manages this enormous task.
