Hello all! I think I’m having a bit of trouble with my home network. It appears that all of my devices are using my Pi-hole DNS because I can see them all listed in the UI. But, when I check the devices, I can see both the Pi-hole IP address and the router’s. Pi-hole is listed first, so I’m assuming everything is using that, but I don’t want the devices on my network to even know about the router DNS. I’ve heard of aggressive devices like Roku exploiting things like this.
I have an ASUS RT-AX55 so I believe I have full control of any setting I need. Any advice? Is this not even a problem?

The DHCP server pushes the DNS configuration to the clients. Is your Asus router running the DHCP server? If so, set the DNS to point to your Pi-Hole

I have my router as DHCP and I also have the DNS set to the pi-hole which I’m assuming is how the devices are getting it. I’m just not sure why it’s getting my router IP as well.

Perhaps because the curent lease has not expired yet. Remove the lease in the router or force the client to get a new lease

Some devices get confused if there is only one DNS server provided by the DHCP… Maybe try setting your PiHole IP for both “Primary” and “Alternative” DNS server

Your router is the gateway to the internet. I could be wrong here, but this is why your devices can see it. They need to know where they can access the internet.
