How does blockerDNS work?
Once signed up, just copy/paste your unique DNS URL into your Android phone's Private DNS setting as shown below, and you're all set! You will have gotten an email with your URL, and you can always sign in
to see your URL as well.
What is DNS?
Cloudflare's website has a great explanation
. To quote them, "The Domain Name Systems (DNS) is the phonebook of the Internet. Humans access information online through domain names, like nytimes.com or espn.com. Web browsers interact through Internet Protocol (IP) addresses. DNS translates domain names to IP addresses so browsers can load Internet resources.
"Each device connected to the Internet has a unique IP address which other machines use to find the device. DNS servers eliminate the need for humans to memorize IP addresses such as 192.168.1.1 (in IPv4)."
What is blockerDNS?
blockerDNS is a DNS service that works just like any other DNS service, translating your google.com request to something like 22.214.171.124 or 126.96.36.199. (You can copy/paste either one into your browser to see how it takes you to google.com.)
blockerDNS has one major difference though. When you visit a website and it requests the IP address for the domain that serves up their ads, and for the other domain that tracks you all around the internet, rather than fetching the IP addresses, blockerDNS instead replies that it doesn't know them. (Actually that's not true, it's slightly more technical but you don't need to worry about that. But if you want to know, read the next paragraph.)
For all blocked domains, blocker
DNS reports the IP address as 127.0.0.1, which points back to the device you're using. It's called the loopback address and for any device you're using it always points to itself. Except your phone obviously isn't serving up ads from itself, so when web sites try to load their ads, well... they just don't load. If you want to read more about the loopback thing, you can check out the Wikipedia article
How is blockerDNS different from ad-blocking apps or VPNs?
Ultimately, you get the same end-result: no ads. But with the apps you're adding extra layers of overhead. Typically, ad-blocking apps are actually an entirely separate browser with its DNS settings altered, and you're stuck using that alternate browser instead of what you actually prefer, like Chrome or Firefox. Other services involve VPN connections or proxies that slow down your whole experience and are just a whole separate headache.
With blockerDNS you aren't installing anything. You're simply pointing your phone to our DNS service instead of the default, which is usually provided by your wireless carrier. Your internet speed doesn't get bogged down - in fact, it'll probably seem faster because you won't be loading megabytes on top of megabytes of annoying ads.
Can I use blockerDNS on any phone?
You need an Android phone running Android version 9 (Pie) or higher. The way we're able to block ads without you installing an app is by taking advantage of an Android setting introduced by Google in 2018 with the release of Pie. If you don't see your version automatically detected below, you can check it manually by going to Settings, followed by the About Phone section.
Do I get a username and/or password to use blockerDNS? How do you know I'm actually a user if all I'm doing is putting in a DNS server in my settings?
The way we handle authentication is by giving you a unique URL to put as your setting. It'll be something like asdfghjkl.blockerdns.com. The first portion is what serves as your "username".
Do you log my DNS requests and track my browsing history?
There is ZERO logging of DNS requests. The ONE thing we keep basic track of is how often your phone pings our servers, solely for the purpose of preventing abuse. And by abuse we mean if you decide to share your unique URL with the entire internet. That said, a reasonable amount of sharing is OK. Go ahead and give your mom your URL if you want.
Is my data at risk if you have a security breach?
It goes without saying that security is taken very seriously. We know that's what everyone says, but please read on.
The only information we store about you is your email address, and the randomly generated unique username that's assigned to you for the custom URL that you would be entering into your phone's "Private DNS" setting. That's it for us!
We can't lose your private data if we don't have it to begin with!
