Domain Name System (DNS) DNS stands for Domain Name System. It is a system that translates human-readable domain names (e.g., www.example.com) into machine-readable IP addresses (e.g., 192.0.2.1). The DNS is an essential component of the Internet and is responsible for mapping domain names to IP addresses. It acts as a distributed database that allows computers to find each other and communicate over the Internet. When a user types a domain name into their web browser, the browser contacts the DNS to obtain the corresponding IP address, which is then used to connect to the web server hosting the website. The DNS also provides other information about a domain, such as email servers and security settings, which enables various Internet services to work. How to change DNS on Android phone: 1.
