Thanks Thierry!

I just committed an Nmap script called dns-ip6-arpa-scan.nse, that
implements the technique.
It uses multiple threads to do the lookup and I was amazed by the result.

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.

Thanks David!

I actually scanned the same segment with a 48 mask yesterday and it worked
great.
Tried you command and it failed. I was having doubts using the same table
for results and pending in the first place.
I've applied your patch in r28379.

Cheers,
Patrik
