README.markdown

Alternative (more granular) approach to a DNS library.

Less is more.

Complete and 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.

Goals:

  • KISS;
  • Symmetric API: client and server side should be very similar;
  • Small API, if its easy to code in Go, don't make a function for it.

Features:

  • UDP/TCP queries, IPv4 and IPv6;
  • RFC 1035 zone file parsing;
  • Fast:
    • reply speed around 35/40K qps (Faster hardware -> more qps);
    • Parsing RRs (zone files) with 80/90K RR/s, that's 5M records in about 58 seconds;
    • This is expected to be optimized further.
  • Client and server side programming (mimicking the net/http package);
  • Asynchronous queries/replies for client and server;
  • DNSSEC;
  • EDNS0, NSID;
  • AXFR/IXFR;
  • TSIG;
  • DNS name compression.

Building is done with the go tool. If you have setup your GOPATH correctly the following should work:

go build dns

Sample programs can be found in the ex directory. They can be build with: make -C ex, or also with the go tool.

Have fun!
