Detailed explanation-1: -Each root name server maintains the host names and IP addresses of top level domain name servers for a company, a university, or other large organizations. The root name server sends your request to the top-level name servers that it knows about.
Detailed explanation-2: -It’s called a Domain Name System, or DNS. In the simplest form, a DNS is a directory of domain names that align with IP addresses. They bridge the gap between computer language and human language – keeping both servers and people happy.
Detailed explanation-3: -The Domain Name System (DNS) maps human-readable domain names (in URLs or in email address) to IP addresses. For example, DNS translates and maps the domain freecodecamp.org to the IP address 104.26.
