toppnivådomänerna

Toppnivådomänerna, also known as top-level domains (TLDs), are the highest level in the hierarchical Domain Name System (DNS) of the Internet. They are the last segment of a domain name, following the dot. For example, in the domain name "example.com", ".com" is the top-level domain. TLDs are managed by the Internet Corporation for Assigned Names and Numbers (ICANN) and its subsidiaries.

There are two main types of TLDs: generic top-level domains (gTLDs) and country code top-level domains (ccTLDs). gTLDs are intended for use by the general public and include well-known domains like ".com", ".org", and ".net". ccTLDs are specific to a country or territory and are denoted by a two-letter code, such as ".se" for Sweden or ".uk" for the United Kingdom.

In recent years, ICANN has introduced new gTLDs to meet the growing demand for domain names. These new gTLDs can be more descriptive and memorable, such as ".tech" for technology-related websites or ".shop" for online stores. The introduction of new gTLDs has expanded the possibilities for domain name registration and has led to increased competition among registrars.

Toppnivådomänerna play a crucial role in the functioning of the Internet by providing a standardized way to organize and access websites. They are essential for the proper operation of the DNS and the overall stability of the Internet infrastructure.
