Dynamic DNS Updates

[Tim Radigan]

Hey peoples,

Have a quick question for anyone who is up for it.  Trying to use DHCP 
to issue Dynamic DNS Updates for my "internal" zone.  I keep getting the 
following error message on the console:

Jun  9 11:00:39 ns2 dhcpd: unable to add reverse map from 
243.1.168.192.in-addr.arpa. to td-webdesign.touchdynamic.com: timed out

I get that for each client on my internal network.  Below are my 
named.conf and dhcpd.conf files edited to remove actual IP's however the 
configuration should be the only thing that matters.

If anyone has any ideas, please let me know.
