Frequently asked questions

We host zero logging DNS servers with support for DNS-over-HTTPS (DoH) & DNS-over-TLS (DoT). Our servers blocks ads, malware, trackers, viruses and telemetry.

Behind this website, and the related services, is a single computer enthusiast who like to tinker with servers, code and similar things at his free time. There’s thus no corporation behind this website and the only source if income (if any) is based on donations.

I often get requests from people wanting to help out with managing the servers. Right now I do not allow anyone other than myself access to them due to privacy and security concerns.

If you enjoy what pi-dns has to offer and want to help out, you can always donate any amount to help out with the server costs. If you want to fund a new DNS server in a new location, we could probably arrange that as well :).

Another great way to help out and keep pi-dns active is to spread the word about us on other websites and forums.

It’s also always fun if you want to participate in the discussion we have in our Telegram discussion group at: https://t.me/pidns_discussion

Do you own/operate hardware and want to host a pi-dns VM? Then contact us a we’ll talk more.

We se pi-dns as a complement to web browser ad blockers.

Most of us use some form of ad blocker in our web browser. These can only block ads that you receive while using the web browser to brows the web. What about windows telemetry? Smart home (IoT) device telemetry? Ads in smartphone apps? Ad blocking for your entire network? This is where pi-dns can help. By setting your router or your devices to use our DNS servers, ads, malware, trackers, viruses and telemetry will automatically be blocked!

If you would like a website to be unblocked, you can fill in our white-list request form at https://ahadns.com/whitelist-request/. If the request is approved, then the submitted domain will automatically be added to our custom white list. This list is automatically propagated to all our DNS servers.

We do not log or store any personal DNS request data. This means that we don’t know anything about what requests a specific user have made. We do keep some anonymized statistics over each server, containing data such as, but not limited to, total number of DNS requests, total number of DNS requests blocked, type of DNS query (A, AAA, CNAME etc)  and type of answer (NOERROR, NXDOMAIN, NODATA etc). These statistics can be seen at https://statistics.pi-dns.com/. The statistics do not contain any information about the content of the DNS request, such as the domain requested, or the requesting IP address.

Our statistics are collected from the utility unbound-control on each DNS server with extended statistics turned on.

Each pi-dns server host its own, local, recursive dns using unbound. This is done to minimize the amount of trust we have to put in others.

All our dns servers use the blocklist oisd.nl.

We really appreciate the work that sjhgvr have put into the blocklist.

Visit the test site dnsleaktest.com and click “Extended Test”.

When the test is complete, the only dns servers visible should be the pi-dns servers that you’ve selected to use when configuring your device.

All our servers are tested for chache poisoning using the DNS Nameserver Spoofability Test by GRC and have passed with an excellent anti-spoofing safety.

Yes, all our DNS servers apply QNAME minimization.

No, our DNS servers does not send EDNS client subnet information.

You can test it with this command:

dig @88.198.91.187 txt o-o.myaddr.l.google.com +short

Compare that to google’s DNS server:

dig @8.8.8.8 txt o-o.myaddr.l.google.com +short
