This guide explains how to enable DNS over HTTPS (DoH) in the Brave browser and route requests through your personal ADnull DNS.
Step 1. Open Brave Settings
Click the three horizontal lines ☰ in the top right corner → Settings.
Step 2. Go to the Security section
Privacy and security → Security.
Step 3. Find Secure DNS
Find Use secure DNS → enable the toggle → select With → from the dropdown choose Custom (Other).
Step 4. Enter the DoH address
Paste the address into the field:
https://YOUR-SUBDOMAIN.dns.adnull.com/dns-query
Replace YOUR-SUBDOMAIN with your personal subdomain — it is shown in the Settings section of your ADnull account.
Click Save.
Done!
Brave now uses ADnull DNS. Ads and trackers are blocked by both Brave's built-in blocker and ADnull DNS simultaneously.
FAQ
Where do I find my subdomain?
Go to the Settings section in your ADnull account — the subdomain is shown in the "DNS Domain" card.
DoH was not applied after saving
Restart Brave and make sure the address is entered without spaces and starts with
https://.
What is the difference between Brave's blocker and ADnull DNS?
Brave's blocker works at the webpage content level (hides elements).
ADnull DNS blocks domains at the network level — before the page even loads.
Together they provide double protection.
