Dnstracer determines where a given Domain Name Server (DNS) gets its information from, and follows the chain of DNS servers back to the servers which know the data.

What's New in This Release:
Better handling of timeout (instead of a static value, start with five seconds and double it each retry)
Warnings are printed if you receive a different RR type than the one you asked for (for example when you ask for an A record and receive a CNAME)
Fixed problems when records received in the authority field are shorter than the domain the nameserver is authoritative for.
When compiled without IPv6 support on an IPv6 capable machine the machine tried to query the IPv6 translated IPv5 address anyway.
-C caches hosts which haven't answered too.
