The Domain Name System (DNS) is one of the most important services on the internet. Its main purpose is to answer name resolution requests.
In analogy to a telephone directory inquiry, DNS should give the corresponding IP address (the "connection number" - e.g. 77.244.243.2) in response to a request with a host name (the "addressee" on the Internet - e.g. www.easyname.com).
DNS stands for "Domain Name System" . It is a system for translating human-readable domain names into IP addresses (Internet Protocol addresses).
DNS plays a crucial role on the Internet as it allows people to use easy-to-understand domain names like "easyname.at" to access websites and other resources on the Internet, rather than having to look up IP addresses like "77.244.243.2 " to remember.
In essence, DNS acts as a kind of phone book for the Internet. For example, when you visit a website in your web browser, your computer sends a DNS query to a DNS server to determine the IP address of the website associated with the domain name you entered. Once the IP address is returned, your computer can find the website and connect.
DNS is an essential part of how the Internet works, enabling billions of websites and services to be easily reached. It is a distributed system where many DNS servers around the world work together to provide resolution of domain names to IP addresses.
