Editing Internationalized domain name (section)

===Example of IDNA encoding===
IDNA encoding may be illustrated using the example domain <code>Bücher.example</code>. ({{langx|de|Bücher|lit=books}}.) This domain name has two labels, ''Bücher'' and ''example''. The second label is pure ASCII and is left unchanged. The first label is processed by Nameprep to give <code>bücher</code>, and then converted to [[Punycode]] to result in <code>bcher-kva</code>. It is then prefixed with <code>xn--</code> to produce <code>xn--bcher-kva</code>. The resulting name suitable for use in DNS records and queries is therefore <code>xn--bcher-kva.example</code>.
