Communication between networks and computers over the Internet is actually communication between IP addresses. When we go online with our PC, we do so based on a unique IP address looking for the physical location (the server) where the information requested is located.
On the Internet, networks, computers, webservers, mail servers and other applications are identified by a unique series of numbers. These numbers are called the IP address and may consist, for instance, of 184.108.40.206.

A U-label is an IDN domain name with special characters, such as belgië.be
An A-label is the ASCII version of a U-label; in other words: an A-label uses ASCII characters only (A-Z, 0-9 and/or ‘-’) to display the domain name. This conversion is carried out automatically by the DNS Belgium registration system. This conversion is required to enable your browser to surf to the correct page. For example, the U-label belgië.be is displayed as xn--belgi-rsa.be when converted to an A-label.
