  • The government will soon roll out a public Domain Name Server, or DNS, for India aimed at providing a faster and more secure browsing experience for Internet users in the country, while ensuring that citizens’ data is stored locally.

What is DNS?

  • A DNS is a like a phonebook for the Internet.

  • Web browsers interact through Internet Protocol (IP) addresses.
  • DNS translates domain names to IP addresses so browsers can load Internet resources.

Indian DNS

  • The roll-out will be executed by the National Informatics Centre – the technology arm of the government.
  • NIC is already using the public DNS within the government network.
  • The users are not mandated to shift to India public DNS. A user is free to choose any DNS.
  • The government’s public DNS, Indian users’ data would be stored within the country, thereby creating a move for Data Localization.

Utility of Indian DNS

  • The main aim of bringing our own public DNS is to ensure availability, particularly for smaller Interest Service Providers (ISPs) who don’t have credible DNS.
  • Bigger ones usually have their own DNS..
  • There are other open DNS servers, including Google Public DNS.
  • The government’s DNS would prevent users from visiting malicious websites.
  • If the government wants to block a website, there is a mechanism in place.
  • The Govt can send a list to the ISPs for reasons such as child porn or fake news, and they have to comply with the order.
