🚀 Glad to present the new release zDNS v0.1.3! 🎉

Following Zero Trust practices, I recently wrote and am slowly beginning to introduce new “blackhole” functionality into the OpenBLD.net DNS ecosystem

zDNS is a DNS server that puts security and control over DNS queries at the center. With new functionality, zDNS now supports regular expressions in hosts.txt files, allowing more flexibility in configuring allowed queries. Now you can use the power of regular expressions to precisely control permissions, including subdomains and patterns.

Main features:

🛑 Denies all DNS queries by default.
✅ Allows you to configure allowed requests through the hosts.txt file.
🔄 Uses balancing strategies to ensure reliable operation with DNS servers.
🛠Easily customizable via YAML configuration.
🔜 Prometheus metrics coming soon

Additional protection of your infrastructure or testing requests with zDNS is possible and may be useful to you! Download the latest version here and start using a DNS server with powerful customization options:

Open Thank You Message.

First of all, thanks to all users of the OpenBLD.net service. Thank you for trusting, service using, contributing and providing feedback.

Some companies, like the people in them, also trust the service and support it with system resources and OSS licenses, which allows the service to grow, be faster, and expand points of presence around the world.

Thanks everyone. I also wrote an Open Tnak You Letter in my blog post to everyone who supported.

Everyone who wants to support, add their logo or name to the project website, support the OpenBLD.net project and receive this benefits.

Peace to all ✌️
