# Alternative (more granular) approach to a DNS library.

Completely usable DNS library. Most widely used Resource Records are
supported including DNSSEC types.

Feaures:

* UDP/TCP queries, IPv4 and IPv6
* TSIG
* EDNS0 (see edns.go)
* AXFR (and IXFR probably)
* Client and server side programming (mimicking the http package)
* Asynchronous queries (client/server)
* RFC 1035 zone file parsing (everything, except multiline records work)

Sample programs can be found in the `_examples` directory. They can 
be build with: `make examples` (after the dns package has been installed)

Everything else should be present and working. If not, drop me an email.

Have fun!
