Answer / Hans Raj Verma
DNS (Domain Name System) resolution in Linux works through a series of steps. When you type a URL into your browser, it first sends a request to your local DNS resolver (usually namedresolver or systemd-resolved). If the resolver doesn't have the IP address for the domain, it queries a root nameserver which directs it to the TLD (Top Level Domain) nameserver. The TLD nameserver then directs it to the authoritative nameserver for the domain, which finally provides the IP address.
