Yes, it is true. Your ISP, or provide should have control over reserve
lookup of your class. With a proper method, they could subnet out a range of
hosts, and delegate them to your name server. Most ISP will play "it can't
be done" or "our software isn't capable" though. You may want to tell them
exactly what to do to make sure who they are dealing with... (redhat
user!!!) *smile*

Someone enlighten Matt and myself, from what I had read/heard, you
delegate authority for reverse lookups of a subnet. Is this true?
At the class C level, of course.
