DoH (DNS over HTTPS) and DoT (DNS over TLS) are two methods that enhance the security and privacy of DNS queries in network communications.

DoH encrypts DNS queries within HTTPS traffic, making them indistinguishable from regular web traffic and difficult to monitor.

DoT uses a dedicated TLS connection for DNS messages, ensuring they are secure from eavesdropping and tampering.

Note: Please be aware that DoH and DoT support varies across router models. The AX series routers, such as the AX55, support both protocols, while the AC series routers currently only support DoH.

For configuring DoH/DoT on an AX/Wi-Fi 6 router

1. Log in to the web-based interface of the router. If you’re unsure how to do so, please refer to How do I log into the web-based Utility (Management Page) of TP-Link wireless router?

2. Navigate to Advanced > Network > Internet in the router settings. If you choose "None" for "DNS Privacy," the router will not encrypt DNS traffic.

3. Upon selecting DoT or DoH, you'll find the "DNS Mode" option. It's generally recommended to use the "Default Mode."

In Default Mode, if the router detects that the chosen DNS servers are unreachable, it will automatically switch to unencrypted DNS to maintain network connectivity.

Conversely, if the chosen servers become unavailable in Ultra Secure Mode, DNS resolution will be disrupted.

4. Below the "DNS Mode" option, you'll find the "DNS Server" section. We've provided a list of commonly used DoH/DoT servers, from which you can select up to three servers simultaneously. 

After setting your preferred DNS servers, click the "DETECT DNS SERVER" button. The router will then automatically verify the availability of these servers.

For configuring DoH on an AC/Wi-Fi 6 router

1. Log in to the web-based interface of the router. If you don’t know how to do that, please refer to How do I log into the web-based Utility (Management Page) of TP-Link wireless router?

2. Navigate to Advanced > Network > Internet in the router settings. Here, you can see the switch for DoH and the server selection field.

When the status is displayed as "connected," this indicates a successful connection to the DoH server.
