martinh's link points to Hurricane Electric's free tunnel broker service.  
Alas, HE's IPv6 service is indescribably
slow; three minutes for 2a07:3b80:0:d95b:68a9:5368:c459:7072 (no servers),  
even longer for 2a05:7cc0:0:185:80:130:250:1
(same, but nslookup finds it right away), HE timed out before answering a  
third IPv6 lookup.

Try nslookup instead:

time awk < IPv6.download.fumuga.com.txt '{ print $2"\t"}' - | nslookup -  >  
IntmNL.IPv6.download.fumuga.com.txt
Took 32 seconds real time to examine 109 fields in the source file; fourteen  
hostnames found.

nMap has been doing much better than nslookup for the IPv4 addresses; of  
three that have finished since I started the
thirteen scripts two days ago, all three completed the scans of all the  
fields in their lists and have found their
hosts to be operating.
