By switching your default ISP’s DNS service to third-party DNS server, it’s easy to do all this. But before moving further, let’s know what DNS is and how many services are there?

The reason why domain names are used is very simple as it is tough for humans to remember IP addresses. It’s easy for them to memorize words say it’s Google, Microsoft, Facebook, Apple or something else than random numbers. So domain names are used for user convenience and they are converted into IP addresses as machines understand only numeric values.  For the same reason DNS is used to translate a domain name to its equivalent IP address. Primarily, DNS is a huge digital address book which contains the list of all websites and their equivalent IP address.

There are many DNS services, but all are not useful and worth knowing. There is a Google DNS for faster speed ( and, OpenDNS for parental control ( and ), and a few others for malware protection and safety. By default people use their ISP’s DNS service, but there are other players if you want extra features. But it depends on you what DNS are useful for you and what features you’re looking.
