# Alternative (more granular) approach to a DNS library.
|
|
|
|
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)
|
|
|
|
Have fun!
