How to use AhaDNS

What is AhaDNS?

AhaDNS is a zero logging encrypted DNS server service supporting DNS over HTTPS (DoH) & DNS over TLS (DoT). AhaDNS servers do not log or save any personal DNS request data. AhaDNS servers automatically block Ads, Malware, Trackers, Viruses & Telemetry. AhaDNS is fully open source. AhaDNS is the brainchild of Fredrik Pettersson. Here is the list of current locations and addresses of AhaDNS servers,

Location	IPv4 Address	IPv6 Address	DoH Address
Netherlands	5.2.75.75	2a04:52c0:101:75::75	https://doh.nl.ahadns.net/dns-query
India	45.79.120.233	2400:8904:e001:43::43	https://doh.in.ahadns.net/dns-query

GNU/Linux without Network Manager:

Open terminal emulator and create a backup of the original configuration file,
```
sudo cp /etc/dhcp/dhclient.conf /etc/dhcp/dhclient.conf.bak

Open /etc/dhcp/dhclient.conf file in your favorite text editor as sudo or root.
In this file look for a line containing something like this,
```
prepend domain-name-servers 127.0.0.1;
```
If such a line exists comment it out like this,
```
#prepend domain-name-servers 127.0.0.1;
```

For IPv4 add following line after it,

prepend domain-name-servers 5.2.75.75, 45.79.120.233;

For IPv6 add following line after it,

prepend domain-name-servers 2a04:52c0:101:75::75, 2400:8904:e001:43::43;

Save the file and close the editor.

Routers:

There are way too many routers out there and their setups greatly vary from one another. Sadly, I can’t possibly cover them all. You can Search DuckDuckGo or Google for changing DNS settings of your particular router. For this article I’ll explain how you can use AhaDNS servers on TP-Link AC1750 router.

Open your favorite browser.
In the address bar type tplinkwifi.net and hit Enter.
Enter your username & password on the login screen.
Click on the Advanced tab. Next click on Network menu button on the left side of the screen. And from the Network options select DHCP Server.
Enable DHCP Server if it is disabled.
For IPv4 in the Primary DNS field enter 5.2.75.75
For IPv4 in the Secondary DNS field enter 45.79.120.233
