Domain name systems (DNS) are a critical part of the Internet. They enable users to find the correct web page by looking up its address in a database.

DNS is run by the Internet Corporation for Assigned Names and Numbers (ICANN).

DNS is a hierarchical system in which each node in the system maps a domain name to an IP address. The top level of the DNS system is the domain name server (DNS).

A DNS query is sent to a DNS server for the domain name of a web page that the user is looking for. The DNS server then looks up the IP address for the web page in its database.

The DNS protocol is based on the hierarchical structure of the Internet. Each domain name is mapped to a unique IP address. The top level of the DNS system is the domain name server.

A DNS server can also cache the IP address of a web page. The DNS server will then not have to query the DNS server for the IP address of the web page.
