Toppdomänssystemet

Toppdomänssystemet, or Top-Level Domain (TLD) system, is a hierarchical system used in the Domain Name System (DNS) to organize and manage domain names. It is the highest level in the DNS hierarchy, and it is responsible for the distribution of domain names across the internet. The TLD system is governed by the Internet Corporation for Assigned Names and Numbers (ICANN), which is responsible for the coordination and management of the TLD system.

The TLD system is divided into two main categories: generic top-level domains (gTLDs) and country code top-level domains (ccTLDs). gTLDs are intended for use by organizations and individuals, and they are not restricted to any particular country or language. Examples of gTLDs include .com, .org, and .net. ccTLDs, on the other hand, are intended for use by organizations and individuals located in a particular country, and they are restricted to that country. Examples of ccTLDs include .us for the United States and .uk for the United Kingdom.

The TLD system is an essential component of the internet, as it allows for the efficient and effective distribution of domain names. It is also an important tool for organizations and individuals, as it allows them to create and manage their own domain names. The TLD system is constantly evolving, with new TLDs being added and existing TLDs being modified or removed. This evolution is driven by the need to meet the changing needs of the internet and its users.
