Completely usable DNS library. Most widely used Resource Records are supported including the DNSSEC types. It follows a lean and mean philosophy. If there is stuff you should know as a DNS programmer there isn't a convenience function for it. For instance I'm pondering if a zone-like structure should be implemented in the library.
Features:
- UDP/TCP queries, IPv4 and IPv6;
- RFC 1035 zone file parsing.
- Fast, reply speed should be around 30K qps (Faster hardware, even more qps). Parsing RRs (zonefiles) goes with 25K RR/s. This is expected to be optimized further.
- Client and server side programming (mimicking the http package);
- Asynchronous queries for client and server;
- DNSSEC;
- EDNS0;
- AXFR/IXFR;
- TSIG;
- DNS name compression;
Sample programs can be found in the _examples directory. They can
be build with: make examples (after the dns package has been installed)
See this mini howto to get things going.
Have fun!
