verkkotunnukseen

Verkkotunnus, often referred to as a domain name, is a human-readable address used to identify and locate resources on the internet. It acts as a unique identifier for websites, servers, and other online services, making it easier for users to access them without having to remember complex IP addresses. For example, instead of typing a series of numbers like 192.168.1.1, a user can simply enter www.example.com.

The system that manages verkkotunnukset is called the Domain Name System (DNS). DNS acts as a distributed database that translates human-friendly domain names into machine-readable IP addresses. When a user types a domain name into their browser, their computer queries DNS servers to find the corresponding IP address, which then allows the browser to connect to the correct server and load the requested content.

Verkkotunnukset are organized hierarchically. The top level of this hierarchy is known as the top-level domain (TLD), such as .com, .org, or .net, as well as country-code TLDs like .fi or .se. Below the TLD are the second-level domains, which are the unique names chosen by individuals or organizations, such as "example" in "example.com". Further levels can exist, creating subdomains. Registering a verkkotunnus typically involves paying an annual fee to a domain registrar.
