Designed for maximum stability and resilience. Our anycast infrastructure is build to ensure continuous DNS service operation even under strong DoS attack.
Our globally distributed DNS anycast infrastructure, with over 80 nodes deployed in 15 strategically selected countries across all continents, ensures highly resilient and stable DNS service.
Our DNS Anycast is built on different DNS server implementations, different routing implementations, different HW vendors, platforms, different colocation and connectivity providers etc. to ensure, that issue with any particular component cannot affect the whole DNS service as such.
Continuous hardware upgrades, increasing network capacity and improving energy efficiency ensure that our DNS platform is constantly evolving to meet new technical and operational requirements.
Key SW components used for the Anycast infrastructure, KnotDNS and BIRD routing daemon, are developen in CZ.NIC labs. Any edge case, performance optimization or security questions are therefore discussed directly with core developers.

We have been working with CZ.NIC since 2022 and using its czech datacenters to operate .UA domain registry. Hosting .UA domain on CZ.NIC DNS anycast infrastructure is another step further providing significant help to Ukrainian internet users, including industrial, government, academic and also military sectors, who all rely on stable operations of .UA domain names. I am thankful to our colleagues from CZ.NIC who becames our key infrastructure partner to ensure reliable operations.
Dmytro Kohmanyuk
Chief Strategy Officer, Hostmaster .UA
We chose CZ.NIC as our DNS hosting partner because they have a modern and secure DNS anycast infrastructure with locations that complement our existing anycast clouds, and because they are known for their reliable operation of the Czech national domain. In the past, we have worked with CZ.NIC on Knot DNS software and have decided to extend our partnership to include DNS anycast hosting services.
