Yet I HAD the !@#$%^& working, and then I screwed it up. It for sure
updated the ptrs file - I saw it in the log, and I saw it when I viewed

There is an option to register the IP in DNS; I suppose I can try
turning that off.

All I want is to be able to type "nslookup the-dhcp-address", and come
back with a hostname. :-)
(and vice-versa)
