Domain Blacklist

The aschi.at Domain Blacklist is an open, privacy-focused project designed to help users and administrators block access to malicious or unwanted domains. This includes ad servers, phishing pages, tracking networks, malware distribution sites, and other potentially harmful or annoying sources.

Unlike centralized blocklist services, this project is community-driven. You can actively contribute by reporting suspicious domains through the reporting form. Submissions are reviewed and stored in a structured database.

The collected blacklist is made available via a simple and lightweight API. It is optimized for use with tools like AdGuard, Pi-hole, firewalls, and even custom browser extensions. Whether you're securing a home network or managing enterprise filters, this service can be seamlessly integrated into your setup.

All processing happens locally – the project does not rely on third-party analytics, cloud services, or external dependencies. You remain in full control.

Start by reporting a suspicious domain via the form, or explore the available API documentation to integrate the blacklist into your environment.

If you think there is a domain blocked as false positive, use the search here and request the removal.
