About the Project and Blocked Domain Lists

Independent Monitoring System Overview

BlokovanéDomény.cz is an independent information portal providing an up-to-date overview and search tool for blocked websites in the Czech Republic. Designed for the general public, consumers, and internet users, the service helps instantly verify the safety of domain names and identify fraudulent e-shops, illegal gambling, or hazardous websites blacklisted by Czech state authorities.

How the Project Works

Our monitoring system automatically downloads and analyzes open data (OpenData) and official registries issued by individual ministries and state authorities at regular intervals. The portal consolidates these fragmented databases into a single, user-friendly search engine. Additionally, for each domain, the system retrieves technical data from the Whois registry and verifies security statuses, such as the implementation of DNSSEC technology.

The provided details are purely informative. The responsibility for the actual listing of a domain on any blacklist always rests with the specific state institution that issued the blocking order.
