Yes, that is what is used on this website...let me create a tar ball  
with the code. Note though: Next version is completely rewritten by  
Jakob Schlyter, and is currently in early tests. That is much better  
design of the code itself, will be perl libraries that are easy to  
include in your other software etc.

My code can be found at http://dnscheck.se/dnscheck.tar.gz

--help give I think all documentation that exists part from what you  
get via the "cat" command.

Example use:

# ./dns.pl --smtp=0 --checkchildren=1 --dnssec=1 --debuglevel=5 -- 
ipv6=0 kth.se
# ./dns.pl --help
USAGE: ./dns.pl [--argument=value ...] command [command-arguments ...]

The following arguments are available (with default values):
            --aslookup 0
       --checkchildren 0
         --checkparent 0
          --debuglevel 3
              --dnssec 1
            --htmlpath .
                --ipv6 1
             --logfile -
         --maxchildren 1
            --maxtries 3
                --smtp 1
          --tcptimeout 15
          --udpretries 4
          --udptimeout 2
           --zonecheck ./dns.pl
