2-cents... I've read that nslookup does not use the same networking 
libraries/kernel routines/whatever that are used by applications (such as 
SSH).  So there is a possibility that nslookup may work, but yous 
application can still fail to reverse lookup.  

I've seen this happen before, where nslookup works, but my Java app 
stalls for 5-min, then continues merrily along.  It's a long shot, but if 
all else fails, try to write a small app to double-check the reverse 
lookup.  (I could write a small Java version of nslookup If you'd like.)
