Model: Archer C6  
Hardware Version: V3
Firmware Version: 1.0.16 Build 20230828 rel.44667

I have configured DOT by android secure DNS feature. But I can still see every hostname in my Archer C6 router parental controls. How this is possible? Is router using reverse DNS or something like that?

Hi  @ZainUlAbdin ,

DNS resolution is encrypted, and normally the router cannot see the records. If there are records, it means that Android's DNS encryption is not in place. You may need to check the settings on Android and consult technical support to confirm the correct steps for the settings.

  Hi@ZainUlAbdin 

 

The router does not obtain the device name through DNS. DoT DNS query is mainly for LAN query. In addition, DoT is set on the router instead of the device, so the situation you mentioned is normal.

If you have other feedback, please feel free to contact us.

Hi  @Joseph-TP 

 

Thanks for the reply. To clarify my question, the router does not have DOT/DOH. the phone is resolving DNS queries using the android Private DNS feature (using DOT). My question is, if the phone is resolving DNS queries, then how is the router's parental control feature showing me every URL that i am visiting? Because DNS queries are encrypted and the router is not resolving them. Router should only know the IP addresses, but still, the router knows every URL.
