Context

The DNS protocol, or Domain Name System protocol, is a fundamental component of networking that translates human-readable domain names into IP addresses. This essential function allows users to access websites and services using easy-to-remember names instead of numerical addresses. Understanding the DNS protocol is crucial for anyone involved in technology, as it plays a vital role in how the internet operates. The DNS protocol is a hierarchical and decentralised naming system used to identify and locate resources on the internet. When a user enters a domain name into their web browser, the DNS protocol is responsible for resolving that name into an IP address, enabling the browser to connect to the desired server. This process involves multiple steps, including querying DNS servers and retrieving the corresponding IP address.

DNS resolver : A server that receives DNS queries from clients (such as web browsers) and performs the necessary lookups to find the corresponding IP address.

Key Points

The DNS protocol translates human-readable domain names into IP addresses, allowing users to access websites and services easily.
Key components of the DNS protocol include domain names, DNS resolvers, DNS servers, and resource records, all of which work together to facilitate efficient Internet navigation.
