From UPSC perspective, the following things are important:
Prelims level: DNS
Mains level: Data Localization and its implications
- 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.
- Humans access information online through domain names, like abcd.com or pqrs.co.in etc.
- Web browsers interact through Internet Protocol (IP) addresses.
- DNS translates domain names to IP addresses so browsers can load Internet resources.
- 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.
