Running a TLD means understanding that Anycast DNS isn’t just a commodity. For TLD operators, fail-safe availability, performance, fast response times and robust protection are non-negotiable. That's the reason RcodeZero DNS is developed specifically for ccTLDs, gTLDs, and IDN TLDs. Built and run by nic.at, we understand the operational reality behind high-availability DNS. We don’t just understand the requirements, we run them every day.
