• Blocking ads, trackers, coinminers, phishing.
• DNS resolver cache and DNS firewall targeting various DNS attack techniques.

FDNS is a community project. We are not affiliated with any company, and we don’t have any commercial goals. Our focus is the Linux desktop. Home users and Linux beginners are our target market.
