* UDP/TCP queries, IPv4 and IPv6;
* RFC 1035 zone file parsing;
* Fast:
* reply speed around 30K qps (Faster hardware -> more qps);
* Parsing RRs (zone files) with 30K RR/s;
* reply speed around 35K qps (Faster hardware -> more qps);
* Parsing RRs (zone files) with 30K RR/s, that 5M records
in about 170 seconds;
* This is expected to be optimized further.
* Client and server side programming (mimicking the http package);
* Asynchronous queries for client and server;
