Release , a high-performance authoritative DNS server (the recursor is made as a separate application) that supports all modern DNS features. The project is developed by the Czech naming registry CZ.NIC, written in C and licensed under GPLv3. The server is focused on high query processing performance, which uses a multi-threaded and mostly non-blocking implementation that scales well on SMP systems. Features such as adding and removing zones on the fly, server-to-server zone transfers, DDNS (dynamic updates), NSID (RFC 5001), EDNS0 and DNSSEC extensions (including NSEC3), response rate limits (RRL) are provided.
In the new release:
- Automatic loading of DS (Delegation of Signing) records into the parent DNS zone using DDNS is provided. Added 'policy.ds-push' option to configure push;
- In case of network connection problems, incoming IXFR requests are no longer
converted to AXFR; - More thorough checking of missing GR (Glue Record) records with addresses of DNS servers defined on the side of the registrar has been provided.
