News: Government will soon roll out a public 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.
- 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.
- The roll-out will be executed by the National Informatics Centre
- It is not that users will compulsorily need to shift to India public DNS. A user is free to choose any DNS
- A DNS is a like a directory for the Internet.
- It is a hierarchical and decentralized naming system for computers, services, or other resources connected to the Internet or a private network.
- It associates various information with domain names assigned to each of the participating entities.
- Most prominently, it translates more readily memorized domain names to the numerical IP addresses needed for locating and identifying computer services and devices with the underlying network protocols.
- It delegates the responsibility of assigning domain names and mapping those names to Internet resources by designating authoritative name servers for each domain.
- It helps to convert domain names that are easy for people to remember into IP addresses, which are used by computers/machines to communicate.
- If the DNS is either slow or fails to work, users will not be able to locate web addresses
