🟩 OpenBLD.net v8 is here – Cache Warming, UNIX Sockets, and More! 🚀

Excited to introduce the next milestone in the evolution of the open DNS service OpenBLD.net! Here’s what’s new:

Speed – UNIX sockets + Caching + Load Balancing
Efficiency – Port reuse allows multiple instances to run on the same port
Load Balancing – Zero logs (except for errors) for maximum performance
Memory Optimization – The core binaries take up just 6MB, with the cache stored in binary form, totaling only 11MB
Buffered Disk Writes – When necessary, writes go through dedicated buffers (tested at 10 million entries in 3.3 seconds)
🔥 Cache Warming – Thousands of domains are preloaded to keep the cache hot, ensuring ultra-fast DNS responses
🔐 Security – Supports Prometheus, SIEM, and Syslog exports for advanced monitoring (for business usage needs)

New mechanisms unlock new possibilities—helping you maintain cyber hygiene, save time, and protect your privacy.

Easy setup: https://openbld.net/docs/category/get-started/
