The Lazy Networker

DNS over HTTPS (DoH) is a protocol that encrypts Domain Name System (DNS) queries and responses between a client (e.g., a web browser or operating system) and a DNS resolver (e.g., Quad9). This encryption protects DNS data from being intercepted, modified, or logged by third-party entities, such as Internet Service Providers (ISPs) or network administrators.

How does Quad9’s DoH service work?
Quad9 offers a DoH service that uses the HTTPS protocol to encrypt DNS queries and responses. When you configure your device to use Quad9’s DoH service, your device will send DNS queries to Quad9’s servers over an encrypted HTTPS connection. Quad9’s servers will then respond with the resolved IP addresses, also encrypted.

How to configure DNS over HTTPS (DoH) using Quad9:
Android (Android 9 and later):
Go to Settings > Network & Internet > Advanced > Private DNS.
Select “Private DNS provider hostname” and enter dns.quad9.net.
Save the changes.

iOS (14 and later):
Note that Apple’s Private Relay feature will override any custom DoH settings. If you want to use Quad9’s DoH, disable Private Relay.
Configure your device’s DNS settings to use Quad9’s DoH by following these steps:
Go to Settings > Wi-Fi > [your Wi-Fi network] > DNS.
Tap “Manual” and enter dns.quad9.net as the DNS server.

Windows 11:
Go to Settings > Network & Internet > Ethernet or Wi-Fi > Change adapter options.
Right-click your active network connection and select “Properties”.
In the “Internet Protocol Version 4 (TCP/IPv4)” or “Internet Protocol Version 6 (TCP/IPv6)” properties, click “Advanced”.
In the “DNS” tab, click “Add” and enter dns.quad9.net as the DNS server.

Other devices and operating systems:
Consult your device’s documentation or manufacturer’s website for specific instructions on configuring DoH with Quad9.

Important notes:
Quad9’s DoH service only blocks malicious domains, not ads or tracking. You may need additional tools to block these types of content.
If you’re using a VPN, it’s recommended to use the VPN’s built-in DNS service instead of configuring DoH with Quad9.
Quad9’s DoH service may not work on all networks or devices due to restrictions imposed by network administrators or firewalls.
