Top-level Domains Blocking If you want to block any top-level domain, just add it without a leading dot to your Denylist. For example, if you want to block access to all websites in the RU domain zone, add ru to your Denylist. Internationalized country code top-level domains should be added to the Denylist list in the IDN form: 中国 (Chinese IDN ccTLD), рф (Russian IDN ccTLD), etc. A full list of top-level domains can be found on the IANA website and Wikipedia. Please note that settings take 5-7 minutes to apply.Stats and filtering status update every 10 minutes.
