Author Switches to Quad9 DNS, Citing 670M Daily Threat Blocks

Summary
Quad9 replaced the author's ISP default DNS to harden a family home network, with the switch described as improving both safety and browsing speed at no cost.
9.9.9.9 was chosen for full malicious-domain blocking; Quad9 also offers 9.9.9.10 without security filtering and 9.9.9.11 with ECS-enabled malware blocking.
670 million malicious domains are blocked on average each day, and the recursive DNS server stops lookups before devices can even reach harmful sites.
Switzerland-based Quad9 says it does not log requests, supports encryption, and operates across 90 countries, which the author says helped deliver privacy and faster response times.
Cloudflare, OpenDNS and Google Public DNS were cited as other free alternatives, underscoring the broader point that ISP-provided DNS often prioritizes convenience over security.
