A Domain is an easy-to-type and remember address that points to a specific, fixed IP address and the website or service behind that IP address.

A Domain Name Registrar is an entity or corporation, such as netcup, that issues new domains by registering them with the ICANN.

The Internet Corporation for Assigned Names and Numbers (ICANN) is a non-profit organization responsible for multiple services that are critical to the proper function of the internet. In the case of domains, its responsibility lies in defining and establishing new Top-level Domains (TLDs).

A domain in use cannot be changed after it has been issued. However, you can change the IP address that the domain currently directs to or use another domain to point to the same or a previously used IP address.
