Services

Quad9 offers several variations of our free, private DNS service.

9.9.9.9 (Secure)

Our most-popular service. A threat-blocking, privacy-first recursive DNS service.

IPv4	IPv6	DNS over TLS	DNS over HTTPS
`9.9.9.9`, `149.112.112.112`	`2620:fe::fe`, `2620:fe::9`	`dns.quad9.net`	`https://dns.quad9.net/dns-query`

For users who want to take advantage of our privacy-first recursive DNS service, but do not want threat blocking, use our 9.9.9.10 service instead.

IPv4	IPv6	DNS over TLS	DNS over HTTPS
`9.9.9.10`, `149.112.112.10`	`2620:fe::10`, `2620:fe::fe:10`	`dns10.quad9.net`	`https://dns10.quad9.net/dns-query`

For users who do not route to the closest-possible Quad9 location, use our 9.9.9.11 for better CDN performance:
