How to block dynamic DNS domains in your browser

Cybercriminals and malware distributors frequently leverage free Dynamic DNS (DDNS) services to temporarily host malvertising scripts or Command and Control (C2) servers, rotating domains rapidly to evade blocklists.

Proactive dynamic host blocking

To keep your firewall robust, it performs asynchronous, read-only requests to multiple independent endpoints, configuring rules at the Address layer that prevent the loading of any scripts hosted on suspicious DDNS services.
