I had replied earlier mentioning that whatever DNS I set as the third DNS server, cloudflare DNS gets automatically added as one of the additional DNS servers by the router.

So looking at my RS600 today, seeing this as default as I guess I had updated FW and had not changed it since last factory reset and setup from scratch:
I'm seeing 3 user changeable DNS sections here:
After setting to Quad9 and SparkLight, it's showing here as being set:
Testing MS EDGE with browserleaks site finds the following:
Test Results Found 39 Servers, 3 ISP, 1 Location
1 from Cableone.Net which is Sparklight now.
6 from WoodyNet.Inc
Rest all from Cloudfare
All locations from Seattle.

Thanks for testing. Can you change the DNS setting to get automatically from ISP and share the DNS settings page? Looks like you have already configured cloudflare as the third DNS before updating the FW?

Just as I thought, it's picking the CF and Google DNS and not the ISP DNS when set to automatic:
Domain Name Server 1.1.1.2
8.8.8.8
1.1.1.1 - coolwifiJun 15, 2026Virtuoso
Was the cloudflare DNS added by the router? How about the automatic DNS setting?

Was set by the router when I select Automatic for DNS.
Same thing is happening on my RS700 as well:
Domain Name Server 1.1.1.2
8.8.8.8I've asked NG to see what is expected behavior for this setting. Prior experiences showed me auto would pick auto detected ISP DNS.
Possible that NG is putting Cloudfare in as a default setting so that DNS points to Cloudfare and the router has something to use over trying to use ISP DNS. Though something NG might put in as a user changeable option. Have a radio button for Automatic that is for auto detected ISP DNS, another option for NG Selected Cloudfare DNS, then the current radio button for user custom input DNS.
