📢 OpenBLD.net IPv6 Pre-Release Testing

Last week, last month, this year... I've been meeting and talking to different people, and they all echoed the same sentiment - IPv6 is needed 💯

A few days ago, I got acquainted with VEESP.com, a company that generously provided OpenBLD.net with an incredibly fast server featuring a high-speed Ethernet connection 🛞

Abstract: Usually, I spend some time testing servers, then assign them a secondary role before introducing them to the production environment. However, this time was different...

I was so impressed 😱 with the veesp.com server's speed that it practically flew into production almost immediately... )

I believe this is a great opportunity to start exploring the IPv6 space. In this month or early 2024, I hope we can begin experimenting with IPv6!

If you're ready to participate in the preliminary testing, please let me know through this OpenBLD.net Pre-Release Testing Form. I will reach out to you directly when the time comes, and together we can strive to make this world even better 🌱

P.S. Thanks to veesp.com and everyone who gives incentive to take a step forward 🤝

🚀 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:
