DNS leak test showing USA cloudflare addresses instead of local NextDNS?
Hi there, I have been using the service for about a week now and have been enjoying the local fast queries and speeds. When I first got my service up and running I had 2 local dns servers powered by nextdns. Now when I am testing for dns leaks I am seeing entries for Cloudflare addresses back to USA - 172.70.37.108
Being in Aus this creates a noticable difference going from <10ms to ~330ms ping response times. Is this a cause of a setting ticked under the performance section in the settings? Again just seeking some clarity about what is causing this. Thanks.
Edit: I have just performed another leak test, no neither NextDNS servers are showing and am getting multiple Cloudflare addresses. I run a PiHole setup and force all traffic through it using the 2x servers provided under my https://my.nextdns.io/ page.

Is it also worth my while just when I do enough of the testing to point directly to the local servers it picks up? Or do those IP's constantly change with regards to nextdns servers? (They differ to what is shown for the 2x ip's shown in my account dashboard) if that makes sense. Thanks!

What do you get for https://test.nextdns.io?
-
NextDNS
{ "status": "ok", "protocol": "UDP", "configuration": "fp0254db39e3be6df7", "client": "my static ipv4 address here", "destIP": "45.90.30.58", "anycast": true, "server": "vultr-syd-1", "clientName": "unknown" } Which is weird because when I run 'leak' tests I seem to get a bunch of USA IP's as well for cloudflare which I've found in the past gives me crap cdn routing and takes ages to resolve pages sometimes. Please see below, my question is should I hard code those 2x highlighted addresses instead of using the provided 2x addresses that are linked to my ip in my nextdns account page. Or do those IP's often change around?

If you configured only the v4 DNS and you didn't configured or disabled v6 you will have leaks.
If possible use DoH or DoT as explained in the links I gave you but probably didn't bother reading.
If you can install the CLI, if not other app/client or some script that can be configured with DoH or DoT. Or disable V6.

*You can try the servers direct ip's, see if they work... I say they won't and I think you should stick with the ones from your profile.

When I sign into my dashboard I even get the following -'IPv6
Your network does not support IPv6'

Bumping for visibility. Is this normal behaviour? When I run these tests I sometimes get only overseas dns server results.. Seems to be really inconsistent and confusing. For instance if I use cloudflare 1.1.1.1 & 1.0.0.1 I only get the two results when I run leak tests.

It's normal to not know, no one was born a master.
To don't listen, to not read to learn, this is not normal.
If you have leaks in DNS where NextDNS and other DNS providers appear on the same time it's probably a problem with v6 which is not configured or can't be configured.
If NextDNS does not appear at all, it is most likely because you did not configured DDNS and your IP is dynamic. I mean is not rocket science. Your IP change, you no longer use NextDNS.
Set the default NextDNS 45.90.28.0 and 45.90.30.0 and it will act just like any other public DNS like Cloudflare or Google. But you will lose all your settings from the account. If you use the IP from your account you need to either have a fixed IP or update it when is changing, manually or to set up a DDNS.
It is all explained in your account, here on Knowledge Base. But it is easier to just complain when is clearly nothing wrong with the service but just human error.
Now, just ignore, again, what I explained and keep having the same problem.

It isn't just me as I can see it appearing on other threads here as well.
To reiterate some of the suggestions you have made. I have IPv6 straight up disabled from my router. I don't have it set up at all and only utilise ipv4. In regards to a dynamic IP that is also incorrect as I have a static ip given to me by my ISP.So rather than telling me I am not listening and ignoring what is said, if we as fellow people in the tech field where does it now take us with the next troubleshooting steps moving forward now you know this information which might I add I already mentioned in the thread previously?

A quick thing and I'm done, one thing is for sure, NextDNS does not redirect you or the others who have problems to Cloudflare or any other DNS providers.
In this situation, there is nothing wrong with NextDNS service. If you don't know or want to learn how to use it, ask someone to check your setup.

Yeah, instead of reading Knowledge Base https://help.nextdns.io/category/knowledge-base
you read on reddit.

Did you link your static public IP from your ISP? If not, you'll need to do that if ipv4 is your only option
If so, do you have more than one static DNS entry setup on your router's side? If so, pihole recommends only having one entry (setup to your pihole's IP)
https://discourse.pi-hole.net/t/how-do-i-configure-my-devices-to-use-pi-hole-as-their-dns-server/245
Your NextDNS ipv4 DNS servers (from your dashboard) will need to be entered as the ONLY custom ipv4 upstream DNS entries via pihole
Or You can use Pihole as the DHCP server instead of the router
