Editorial note: This entry was written on 10/10/2021. Unfortunately, the provider (at that time) had difficulties with his website (help.comodo.com redirected you too many times.) which is why we worked with archived versions of these websites (as far as possible) for research.
Editorial note: The official documentation of Comodo Secure DNS is not in good condition. It looks unkempt and outdated. For example, instructions for installing the server on Windows Vista and XP are provided, and nothing is mentioned of all other versions of Windows. That’s why we can’t offer a lot of information about the DNS server. We ask for your understanding in this regard.
