The Domain Name System (DNS) is a hierarchical, decentralized, and distributed database that provides the translation of domain names (e.g. example.com) to IP addresses.
DNS was originally developed as a project of the United States Defense Advanced Research Projects Agency (DARPA) in the early 1990s. DNS is now a global infrastructure operated by ICANN.
The DNS serves two primary purposes: hostname resolution and name service management. Hostname resolution is the process of translating a domain name (e.
com) into an IP address. Name service management is the process of managing the DNS database and resolving queries.
DNS is a vital part of the Internet infrastructure and enables users to locate information about resources on the Internet. For example, a user can type in the domain name of a website, such as www.example.
com, and the DNS will return the IP address of the website’s server. DNS also enables users to access Internet resources by entering their domain name rather than the server address.
DNS is a distributed database, which means that it is not hosted by a single organization. Instead, the DNS is hosted by ICANN, a global organization that manages the DNS.
This distribution makes the DNS more resilient to attack and allows for greater flexibility in how the DNS is used.
One of the benefits of the DNS is that it is decentralized. This means that the DNS is not controlled by a single organization or government.
This decentralization is important because it allows for greater flexibility and freedom in how the DNS is used.
In addition, the DNS is hierarchical. This means that the DNS is divided into different levels, or domains. At the top of the DNS hierarchy is the root zone, which is a collection of DNS records that specify the authoritative addresses for all other domains. The root zone is maintained by ICANN and is updated regularly.
Below the root zone is the top level domain (TLD), which is the most common type of domain. TLDs are subdivided into second level domains (SLDs), which are subdomains of TLDs. SLDs are divided into third level domains (3LDs), which are subdomains of SLDs, and so on. This hierarchy makes it easy for users to locate the resources that they are looking for.
Finally, the DNS is distributed. This means that the DNS is not hosted by a single organization or government.

Domain name DNS is a system that helps computers find the correct website or email address when someone types in a name or address into a browser or email program. Domain name servers are computers that are specially configured to help with this task. When someone types in the name of a website, like google.com, the Domain Name System (DNS) looks up the name in a database of registered domain names.
