So, i normally use 1.1.1.1 etc for my DNS servers rather than the ISP supplied ones, and for some reason, if i change them, i still seem to be routed through the ISP servers as well as the CF ones.
If i leave them set to ISP supplied DNS servers, i only get theirs listed using the below test website.

Surely i should only see the Cloudfare servers if i change them and not the ISP ones as well?
Or am i not understanding how they work?
What Router do you have. When connecting to the WAN (ISP) you have a choice of accepting the Default DNS or using your own. This is the case with my Asus router. I can say no to the automatic DNS and set my own. Separately, I can set the DNS for any client in DHCP setup. Lastly, I have the option of either advertising the router DNS in addition to the DHCP DNS. Most routers will always advertise their own address for DNS, regardless of whether you have set the DNS in LAN/DHCP. IF you have accepted the automatic WAN DNS in WAN configuration, then as far as I'm aware, all Windows PC's will accept 3 DNS addresses when obtaining a lease, the ones you specify in DHCP AND the Router IP, which will then route to the ISP DNS servers. As for other devices, cannot tell you, hit and miss as to whether they accept the router DNS as well.
I have a new Netgear RS300, but i get the same problem with the ISP supplied router.
If i use Cloudflare, when it reconnects, it seems to just drag in the ISP DNS when i look at the PPP reconnection.
This is the ISP router log with manually configured Cloudflare DNS

Unfortunately the log tells me what it's doing, not what you've configured. Need to see a screenshot (obscure any username or in the clear password) of your internet settings page(s) and the LAN/DHCP pages(s). The pppoe settings are the likely culprit

Ok ill put the ISP router back in and grab some screenshots.
Thing is, i get similar results whichever router is in place.
I also had an old Technicolor router that i tried, and that seems to only connect to the ISP DNS regardless as well!

It showed Cloudflare for me too which I do not have configured.
All other DNS checkers show correctly as mentioned so it is something specific to this one. ]
You are blocking DNS queries on port 443 then? Now days DNS is more complicated to block.

I just tested the link over my friends connection, and cloudflare isnt listed, just his ISP DNS servers.
Personally I wouldnt be automatically blaming the test but looking instead for the leak. I had someone else in another thread a while back saying the same thing about the browserleak dns test, he was adamant his config was sound so I gave up on it.

You forgot to mention Amiga. 😢
Nor did I mention a networked DOS machine, nor a DEC VAX; or any of the other legacy kit I've tried in years gone by. My point was that posting a Windows/DOS command isn't necessarily represenative of what people are using in 2024.

My point was that I was giving the command for the most-used OS and people using a lesser-used OS will most likely know their equivalent without me having to spell it out.
But in future I will most likely have to add "or whatever your OS's equivalent is" to satisfy the pedants.

Ok so i have been through all the settings and everything is set up as it should be eg, Manual DNS entry etc.
Posting screenshots of the WEB gui is difficult as the most i can get in one screen shot is one setting.
The layout of the Netgear settings is quite poor tbh!

To be fair, most GUI's have their issues, Asus included, where things are buried deep!
There is no reason for this to occur if you have set at the WAN and DHCP settings page the DNS entries you want to use.
The only remaining item is IPv6. Do you have both IPV4 and IPv6? DNS is separate for both, wonder if the router is handing out IPV6 addresses with the ISP IPV6 DNS server...
Certainly, when I configure IPv6, again, you can accept the default from ISP or set your own.

Interesting you bring up IPV6.
With the isp router, i disabled IPV6 as it doesnt seem to work at all when testing, and yet is fine on the NETGEAR.
However, i have just put the NG back to ISP DNS on V4 and disables IPV6 and on the test it appears to sill have V6 detected?

Edited to add:
Just put v4 DNS back to Cloudflare and Google and after another test, the ISP DNS seems to be gone, however, they are still detecting IPV6?
They all seem to take a hell of a route!

Also, i thought i would manually set V6 DNS but on the router, there seems to be too many 'spaces' to enter them.
