Nimipalvelin, often referred to as a DNS (Domain Name System) server, is a fundamental component of the internet's infrastructure. Its primary function is to translate human-readable domain names, such as www.example.com, into machine-readable IP addresses, like 192.0.2.1. This translation process is essential for navigating the internet, as computers communicate using numerical IP addresses, not familiar domain names.

When a user types a domain name into their web browser, the request is first sent to a local nimipalvelin, typically provided by their internet service provider (ISP). If this local server has the requested IP address cached, it returns it directly to the user's computer. If not, it forwards the request to other nimipalvelimet in a hierarchical system. This process involves contacting root name servers, then top-level domain (TLD) name servers (e.g., for .com or .org), and finally authoritative name servers for the specific domain.

The nimipalvelin system is distributed globally, with thousands of servers working together to ensure efficient and reliable name resolution. This distributed nature makes the internet resilient, as the failure of a single server does not bring down the entire system. The speed and accuracy of nimipalvelimet are crucial for a seamless internet experience, impacting everything from website loading times to email delivery. Without nimipalvelimet, the internet as we know it would be unnavigable.
