Thanks, Konstantin, for the thorough response! I was failing to grasp that the forward lookup portion of the method was failing because there was no forward dns mapping. I thought it was failing locally inside the java code, not in the dns system.
To confirm the lack of a dns mapping, I used "host <ip address>" and received a host name. Then I tried "host <host name>" and got a host not found message. Since it's not critical that I prevent spoofing in my app, I'm using a variation of the jndi dns code you pointed out in http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4670102.
