About Adblock DNS Server
Adblock DNS Server is a Docker-based project that runs a DNS server using Bancuh DNS and dnsdist-acme. It functions like a regular DNS server but returns an unroutable IP address for known ad domains, and can also block tracking servers, malware sites, and adult content. It includes a preloaded blocklist compiled from multiple host file sources, with scripts provided to customize the list.
It requires a Linux server with Docker Compose v2, SSH access, and port 53 available, with additional ports for DNS over TLS, DNS over HTTPS, and Let's Encrypt when TLS is enabled. A VPS with a public static IP is recommended for shared use, while a local Linux computer or virtual machine can be used for testing.

Adblock DNS Server FAQ
How does the Adblock DNS server block ads?
It resolves domains for known ad services to an unroutable IP address, so browsers and apps cannot connect to the servers hosting the ads.
What is needed to run it?
A Linux server OS with Docker and the Compose v2 plugin, SSH access, and port 53 free. A VPS with a public static IP is recommended, or a local Linux computer or virtual machine for experimenting.
How large is the default blocklist and what resources does it use?
The default configuration blocked about 7 million domains measured at the end of September 2026, and the two containers used about 200 MB between them on a server with 1 GiB of RAM.
