Imagine typing the name of the person you want to call instead of the phone number. That would be very practical, since names are much easier to remember than numbers. DOMAINs offer this convenience on the Internet.
Computers connected to the Internet communicate with each other using numerical IP addresses that uniquely identify each computer. An example of such an IP address is: 188.8.131.52. The Domain Name System DNS allows the use of DOMAINs instead of the IP address. The switchplus website can thus not only be reached via the IP address of the web server https://184.108.40.206, but also via the DOMAIN https://www.switchplus.ch. DOMAINs, like IP addresses, must be unique, which is why DOMAINs are assigned by a central registry operator.
