suresh The Purpose of DNS Root Servers in the Domain Name System
DNS root servers play a crucial role in the domain name system by providing the starting point for resolving domain names to their corresponding IP addresses. These servers are at the top of the hierarchical DNS structure and store information about the top-level domains (TLDs) such as .com, .org, .net, etc.
When a user enters a domain name into a web browser, the browser sends a query to a DNS resolver which then contacts a DNS root server to begin the resolution process. The root server directs the resolver to the appropriate TLD server which then further resolves the domain name until it reaches the authoritative name server for the specific domain.
Overall, DNS root servers play a crucial role in the efficient functioning of the internet by helping to translate human-readable domain names into machine-readable IP addresses.
