DOC Checks the integrity of a domain; maintained by Brad Knowles. This version works with BIND 9, but there is also a version for BIND 8. (version 2.2.3 of 25-Jul-2001, checked 08-Sep-2004)
dnswalk is a DNS database debugger. It works by initiating a zone transfer of a current zone, inspecting individual records for inconsistencies with other data, and generating warnings and errors. It is not a parser of DNS datafiles, it works strictly via existing DNS query methods on a "live" system (however dnswalk can be run on a separate nameserver which has data ready to move into production)
Here is dnswalk-2.0.2.tar.gz. You must use recent version of Perl, at least Perl 5.003. You MUST install Net::DNS, found either from a CPAN site or from Michael Fuhr, the Net::DNS author. Net::DNS also requires the Perl IO module, (for IO::Socket) at least IO-1.15.
Sleuth is a simple Perl script for checking DNS zones for bugs and other inconsistencies. It should check all zone requirements mentioned in the corresponding RFCs plus several other common errors. The package also contains a trivial (but useful) WWW interface.
scandns.pl is a command line script which will take a (sub)network entered by the user and check all the reverse DNS records for that network. scandns then checks the forward records of the hosts returned by the initial scan and reports any inconsistencies. This is quite useful for cleaning up old inverse records, as well as general network maintenance and security.
nslint is a lint-like program that checks DNS files for errors. DNS or Domain Name System generally maps names to IP addresses and E-mail addresses in a hierarchical fashion. Errors detected include missing trailing dots, illegal characters (RFC 1034), records without matching PTR records and vice-versa, duplicate names in a subnet, duplicate names for an address, names with cname records (RFC 1033), missing quotes, and unknown keywords.

Dlint analyzes any DNS zone you specify and reports any problems it finds by displaying errors and warnings. Then it descends recursively to examine all zones below the given one (this can be disabled with a command-line option).

ZoneCheck is intended to help solve DNS misconfigurations or inconsistencies that are usually revealed by an increase in the latency of the application. The DNS is a critical resource for every network application, so it is quite important to ensure that a zone or domain name is correctly configured in the DNS.
The dnsutl package is a collection tools to make administering DNS easier.

A libnet/libpcap-based DNS sniffer/spoofer.
dennis is an automated DNS builder. It takes an /etc/hosts style file and outputs information suitable for a bind 4/8 master and secondaries. This software is currently alpha, that is it works for me, I've cleaned up enough stuff to make dropping this into place not too hard for other sites but there remains a hefty chunk of work left to do. I would appreciate any offer to help since I do not have a lot of time to work on this. I have included a syntax checker to catch any potential problems.
DNSdoctor is a tool based on zonecheck that is intended to help with solving misconfigurations and inconsistencies in DNS zone files. It features a powerful configuration file, does not depend on policies, fine grained test selection (by test, categories, or zones), full IPv6 support (connectivity and AAAA records), and several input/output interfaces (CLI, GUI, CGI, and a dedicated mode for use inside shell scripts). It uses threads to cut down checking time and can be extended with new tests, interfaces, and reports, and features exception and cache mechanisms to simplify test writing.
