What is the root domain name server?

Root name servers are the foundation of DNS and are responsible for managing authoritative records for all top-level domains (TLDs). They are essentially the "phone book" of the Internet, converting domain names into IP addresses. They work by providing the address of the authoritative nameserver responsible for that top-level domain when the user enters a domain name. Root name servers are critical to the proper functioning of the Internet as they allow users to access any website, and are operated and maintained by ICANN to ensure the stability of the Internet.

What is a root domain name server?

Root name servers are the foundation of the Internet's Domain Name System (DNS) and are responsible for maintaining authoritative records for all top-level domains (TLDs) such as .com, .net, and .org. They act as the Internet's phone book, translating domain names (such as www.example.com) into their corresponding IP addresses (such as 192.0.2.1).

How does the root domain name server work?

When users enter a domain name into their browser, their requests are sent to the root name servers. The root name server examines the requested top-level domain and returns the address of the authoritative name server responsible for that top-level domain. The authoritative name server then returns a record pointing to the IP address of the domain name.

Why is the root domain name server important?

Root domain name servers are vital to the proper functioning of the Internet as they allow users to access any website. Without root name servers, users would not be able to resolve domain names to IP addresses and thus would be unable to access anything on the Internet.

Maintenance of root name servers

Root name servers are operated and maintained by the Internet Corporation for Assigned Names and Numbers (ICANN). ICANN regularly updates and maintains root name servers to ensure the stability and accessibility of the Internet.
