Over the past 15 years, RcodeZero DNS has evolved from a small internal Anycast project at nic.at into a globally trusted DNS service, now supporting more than 30 million domains. A key driver of this success is its robust and flexible Secondary DNS solution, paired with a continuous development and a strong customer-first approach. What started with just a handful of locations has grown into a powerful global infrastructure for registries, Internet Service Provider and organizations. Today, the Anycast service operates more than 60 nodes worldwide across two independent clouds in two autonomous systems (AS) with 26 different providers.

"The Internet is permanently changing. Providers come and go, and routing changes due to defect backbone links or business decisions,” says Klaus Darilion, Head of Operations and a key figure in the development of RcodeZero DNS. “Therefore, we constantly monitor our routing performance and BGP optimizations are our daily business to fulfill our low-latency promises.”

Trusted by leading Internet Service Providers

RcodeZero DNS supports flexible deployment models: The DNS infrastructure can be fully outsourced or complemented with Secondary DNS alongside existing systems. This allows organizations to enhance resilience without sacrificing control, which is one of the main reasons why the service is trusted by major international Internet Service Providers with millions of domains. Also, external nameserver monitoring consistently ranks the RcodeZero DNS network among the most reliable Anycast services worldwide.

“For us, reliability and stability are non-negotiable. With RcodeZero DNS, we found a partner who not only delivers excellent technical performance but also understands our operational needs. That’s why we have chosen the service 10 years ago and why we continue to rely on it,” says Mario Peschel, CEO of INWX.

Security built in: DNSSEC and DDoS protection

Security is a fundamental part of the offering. DNSSEC is included by default in every package. “DNSSEC is a complex and specialized topic that we handle very well. Many registrars prefer to outsource this service to experts,” knows Robert Schischka, CEO of nic.at and ipcom. In addition, the entire network is protected by independent, globally active DDoS mitigation providers, safeguarding services even during large-scale attacks.

Competing with market leaders through service and flexibility

In a market dominated by large global providers from the United States, RcodeZero DNS differentiates itself through service quality, flexibility and customer proximity, built and operated under European jurisdiction. As a smaller, agile provider, ipcom can respond quickly to customer requirements, implement tailored solutions and provide direct, personal support – without the complexity of large-scale organizations. This combination of responsiveness and technical expertise is a key advantage for ISPs that require both: reliability and adaptability.

“What convinced us from the beginning was the combination of flexibility, strong support and a highly resilient infrastructure,” adds Daniel Strauß, CEO of InterNexum. “The team behind RcodeZero DNS listens, adapts and evolves with us. This long-term partnership gives us confidence for the future.”

This partnership-driven approach enables ongoing innovation, whether through infrastructure upgrades, new features or customized integrations. In addition, it builds long-term relationships based on trust and transparency.

Perspectives for the next 15 years

As the digital ecosystem continues to evolve and security challenges intensify, the demand for reliable DNS solutions will continue to grow. With its proven infrastructure, built-in security and strong service orientation, RcodeZero DNS is ideally positioned to support ISPs and organizations in delivering stable, secure, and high-performance DNS services – now and in the future.
