This is really awesome, and thanks for doign it so quickly. However I
couldn't get it to run properly when trying to map the addresses around
nmap.org; I always got an error.

NSE: 'dns-ip6-arpa-scan' (thread: 0x175de40) threw an error!
/home/david/nmap-git/scripts/dns-ip6-arpa-scan.nse:70: attempt to concatenate local 'f' (a table value)
stack traceback:
        /home/david/nmap-git/scripts/dns-ip6-arpa-scan.nse:70: in function 
</home/david/nmap-git/scripts/dns-ip6-arpa-scan.nse:52>
        (tail call): ?

I made these changes and now it seems to work.
