Internationalized Domain Names

Internationalized Domain Names (IDNs) represent domain names in non-Latin or extended Latin languages, such as Russian, Chinese, Cyrillic, Arabic, etc. Since internet DNS servers cannot natively process the characters of these languages, they employ Punycode to convert Unicode characters into ASCII.

If you are a DNSFilter customer located outside of the USA and need to add IDNs to your Allow/Block list, you should first input the native domain name into a converter like Punycoder.com. Subsequently, you should input the resulting punycode version into your policy's Allow/Block list.
