Panix Help System: International DNS

If your domain name uses non-ASCII characters:

Some domain names include characters that aren't included in the standard (ASCII) character set. If you are registering such a domain, it must be encoded properly so that the appropriate characters will be displayed in users' applications. This encoding is called IDNA (Internationalized Domain Names in Applications).

You will have to encode your domain name before we can add it to our server.

Details of IDNA may be found in RFC 3490.

Details of PUNYCODE are in RFC 3492.
