Release Notes: The timeout command line parameter was re-integrated. IPv6 root server handling was fixed. A lame server issue with certain domain names was fixed.

Release Notes: Handling of timeouts was improved: instead of a static value, an initial value of five seconds is used, and is doubled with 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). Problems which occurred when records received in the authority field are shorter than the domain for which the nameserver is authoritative were fixed. When compiled without IPv6 support on an IPv6 capable machine, the machine tried to query the IPv6 translated IPv6 address anyway.

Release Notes: This release adds support for SOA records.

Release Notes: Added support for PTR records, and fixed some annoyances.

Dnstracer is actually a great tool for dns traversal check up.
I recently started using this www.squish.net/dnscheck/ and was thinking if output statistics of dnstranser be modified to show result as in percentage like how many % of servers returned authoritative answer and how many of them returned failures.
Thanks.
Abbas.

DJB's dnstrace differences?
What is the difference between this and DJB's dnstrace (included in his djbdns package)? His dnstrace traces down all domain names from the root and does a great deal of output. URL: cr.yp.to/djbdns.html (cr.yp.to/djbdns.html)
