AdGuard Cloud DNS

Hi,

is there a reason why you do not recommend AdGuard DNS (Private and paid one)? The service itself is quite similar to what NextDNS and Control D is offering.

Any reason why AdGuard is not on the list?

Because it is paid ?

But the same as the others… Talking about the paid ones section. NextDNS and ControlD also cost money?!

Well, I did a trial with them and I have no idea what they are doing. A managed DNS supposed to use their own DNS servers, right? Nope. They are using Cloudflare and Google DNS.

Thanks for the detailed information.

Can you give us the links within the AdGuard Feedback Mail? Would like to read them.

Still very confusing. NextDNS is also clean and doesn’t have this issue.

Sure

I’m also thinking about which is the best to choose.

On my list:

  • AdGuard DNS
  • ControlD
  • NextDNS

Looks like AdGuard DNS is a bit of a favorite. But don’t know if I should trust it at all. Yes, they’re EU now (Cyprus Office). But all the people behind are mostly still in Moscow.
Maybe better going with NextDNS (no EU company) or ControlD (Windscribe company from CAN).

In my opinion i have tried all of them but personally i liked all of them.
You can go with any of this option.
For me i am a nextdns user premium user for about 4years or so.
And controld is very new in this market but this is also good i have used adguard but there logs are not that good they say they provide logs for premium users only but you need to serve free users at least for trial.
Like controld to experience the service.
That was not there in adguard.

Did you try https://adguard-dns.io ? Even in free mode there are really good logs within their dashboard.

For me AdGuard has one of the best web dashboards… But I do have some issues with services not connecting.

Only the first 300,000 requests are free, then after that like next DNS. It’s normal web browsing without blocking. AdGuard home is suggested, which is a self-hosted version of AdGuard DNS web. So why not web itself? Buy subscription | AdGuard DNS

Not necessarily.

What the screenshot is showing are NS records hosted with Cloudflare & Google. If so, hardly consequential for a resolver.

What’s the cmd that you ran?

What issue? The NS records [with AdGuard]? To me, it is a non-issue.

Good point. It is listed under Recommended Providers, just not under cloud hosted. Not really sure why, maybe it was not as customizable at that time?

DNS providers are not %100 owning their own infrastructure, that is correct, but that doesn’t mean nearly all of my DNS queries should go to Cloudflare or Google, and use DNS servers from another continent. Only Adguard does this. NextDNS and Control D don’t have this problem.

You’re right, your DNS queries shouldn’t.

My question was: How are you reaching this conclusion from the screenshot you shared (which shows NS records)?

What cmd / tool are you using to ascertain your hypothesis?

I am using dnscheck.tools site to check the DNS

Thanks. I looked at the dnscheck.tools code. Those aren’t NS records.

The results for AdGuard DNS does show Google & Cloudflare IPs but it could be that AdGuard fronts their resolvers over Google-owned / Cloudflare-owned IPs (ref)? dnscheck.tools cannot necessarily know if AdGuard is “leaking” queries to Cloudflare / Google DNS resolvers.

For instance, many here mention NextDNS, which shows DigitalOcean, but that doesn’t mean they forward queries to Digital Ocean’s resolvers.

If AdGuard’s use of Google / Cloudflare infrastructure worries you, (not to single out but since it is discussed here & recommende by PG) NextDNS should as well. They use (used?), afa I can tell, Cloudflare as a CDN, AWS as a host, and Google for some kind of logs streaming.

It needn’t be a “leak” the way you think it might be. Though, only AdGuard can confirm that, for sure.

Yes, they can rent server from Google or Cloudflare or any other providers, that is not the issue.

Check below pictures for example.

It is clear that something is wrong with Adguard.

Maybe @ameshkov can jump in and give us some details. He is the CTO and already posted over here.

I’m also interested into clarification.

Hi, we can use CF or Google as a fallback in the case when the domain’s nameserver times out.

We thought about how to improve the fallback algorithm to minimize these queries but haven’t yet got to it: Try to improve the fallback approach · Issue #654 · AdguardTeam/AdGuardDNS · GitHub

Generally, the issue is rare, but unfortunately it’s visible on dnscheck.tools because their nameservers time out pretty often.

This is AdGuard DNS not Adguard Cloud DNS right?
