release , a high-performance authoritative DNS server (the resolver is implemented as a separate application), supporting all modern DNS features. The project is developed by the Czech domain registry CZ.NIC, written in C and under the GPLv3 license. The server is distinguished by its focus on high query processing performance, for which a multi-threaded and largely non-blocking implementation is used, well-scalable on SMP systems. Features include adding and removing zones on the fly, zone transfers between servers, DDNS (dynamic updates), NSID (RFC 5001), EDNS0 extensions, and DNSSEC (including NSEC3), response rate limiting (RRL).
In the new release:
- Automatic loading of DS (Delegation of Signing) records into the parent DNS zone has been ensured using DDNS. The option ‘policy.ds-push’ has been added for configuration.
- In case of network connection issues, incoming IXFR requests are no longer
converted to AXFR; - A more thorough check of missing GR (Glue Record) entries with DNS server addresses defined on the registrar's side has been implemented.
