The rules for valid domain names are not the same for all registry operators.
Please note that Swizzonic offers a subset of these regulations:
For DOMAINs, the minimum length of the DOMAIN is 3 characters and the maximum length is 63 characters. All characters between “www.” and “.your TopLevelDomain (e.g. .ch)” are counted.
Exceptions are DOMAINs with umlauts and special characters (IDN: Internationalized Domain Name). Because the Domain Name System does not support these characters, an ACE string must be translated “in the background”. In the case of an IDN, the translated characters will be counted as the ACE string:
www.swizzonic.ch is 9 characters long.
www.bücher.ch is not 6 characters long,
ACE string: xn--bcher-kva.ch, but 13 characters long.
Please note that IDN are not yet supported by default everywhere. The functioning of such DOMAINs cannot be guaranteed in every case. It is recommended not to rely on one IDN alone for important applications.
DOMAINs can contain characters from the following character set:
a b c d e f g h i j k l m n o p q r s t u v w x y z
0 1 2 3 4 5 6 7 8 9 –
For the TLDs .ch, .li, .de and .eu, the following IDN characters are also permitted:
à á â ã ä å æ ç è é ê ë ë ì í î ï ð ñ ò ó ó ô õ ö ø ù ú û ü ý þ ÿ
For the TLDs .biz, .com, .info, .name, .net and .org and most new generic domain names (gTLD), the following IDN characters are also allowed:
ä ö ü
Unfortunately, no generally valid statements are possible for the country domains (CC-TLD). The general terms and conditions of the register operators can be found in our General Terms and Conditions. If you have problems with registration, please contact our helpdesk. We will be happy to help you.
The DOMAIN must not contain a hyphen as first character, as third combined with the fourth character and/or as last character (e.g. “-hello.ch”, “ha-llo.ch”, “hello-.ch”).
