info

DNS over HTTPS (DoH) is a protocol for performing remote DNS resolution via the HTTPS protocol. A goal of the method is to increase user privacy and security by preventing eavesdropping and manipulation of DNS data. DoH encrypts the data between the DoH client and the DoH-based DNS resolver. The names of remote servers accessed by the user using DoH are hidden.

For correct DoH operation, select Any in the Allowed certificates drop-down list of the Dr.Web GUS tab.

•DNS servers—List of DNS servers, which replaces default system list.

•DNS domains—List of DNS domains, which replaces default system list.
