Question

What is DNS???

Accepted Answer

DNS stands for Domain Name System. It is a decentralized naming system that translates domain names into IP addresses.

DNS is used to convert human-readable domain names (e.g., www.example.com) into IP addresses (e.g., 192.0.2.1).
It helps in the efficient routing of internet traffic by mapping domain names to their corresponding IP addresses.
DNS also provides other important information, such as mail server records (MX records) and text records (TXT records).
It operates through a hierarchical structure of DNS servers, including authoritative DNS servers, recursive DNS servers, and root DNS servers.
DNS caching is used to improve performance and reduce network traffic by storing previously resolved domain name-to-IP mappings.

Accepted Answer

Domain naming systems resolves IP address to the hostname and hostname to IP address.
