Domänadresser

Domänadresser, often shortened to domäner, are unique identifiers for websites on the internet. Think of them as a human-readable address for a specific location on the World Wide Web, making it easier for people to find and access online resources without needing to remember complex numerical IP addresses. A domain name typically consists of at least two parts separated by a dot. The part to the left of the dot is the second-level domain (SLD), which is usually the name of the website or organization. The part to the right of the dot is the top-level domain (TLD), such as .com, .org, .net, or country-specific ones like .se for Sweden or .uk for the United Kingdom.

When you type a domain name into your web browser, your computer contacts a Domain Name System (DNS) server. This server acts like a phonebook for the internet, translating the human-friendly domain name into the corresponding IP address that computers use to locate the server hosting the website. Domain names are hierarchical, with the TLD being the highest level. They are crucial for branding, online identity, and facilitating easy navigation on the internet. Registering a domain name grants an individual or organization exclusive rights to use that specific name for a set period, preventing others from using the same address.
