Open source innovation.
Mission critical reliability.

We’re a nonprofit foundation building open source technologies that keeps the internet’s core — DNS and routing — secure, resilient, and always on.

We don’t just write code. Through software, standards, and expert support, we keep critical infrastructure running for everyone, everywhere — open, trusted, and built to last.


Resilience and uptime isn't negotiable

“You can’t afford downtime. And you shouldn’t have to gamble on unreliable support.

That’s why we deliver open-source infrastructure—with direct access to the people who built it. No ticket queues. No intermediaries. Just answers.”

We help keep mission critical networks running

“No news is good news. When your infrastructure is stable, invisible, and quietly doing its job—that’s success.

We help make that happen, so you can keep the world connected without worrying about what's under the hood.”
