DNSCheck from IIS and Zonecheck from AFNIC are two different software packages that do DNS validation of the quality of a DNS delegation. AFNIC and IIS decided to develop a new DNS validation tool from the scratch under the name "Zonemaster".

The Zonemaster implementation intends to be a major rewrite of the existing DNS validation tools developed by AFNIC (Zonecheck) and IIS (DNSCheck), and implement the best parts of both.


The components developed as part of the Zonemaster project will help different types of users to check domain servers for configuration errors and generate a report that will enable to fix the errors.

The ambition of the Zonemaster project is to develop and maintain an open source DNS validation tool, offering better performance than the existing tools and provide extensive documentation which could be re-used by similar projects in the future.


The repository you are looking at is the main project repository. In this repository, documentation regarding the design, requirements and specifications for the zonemaster implementation are available.

Also, in this repository, you can find a brief user guide.
