reverse cidr zones

[Jeff Stevens]

Well, if we have the zone 192-255.185.145.12.in-addr.arpa. defined, does 
only the parent zone (at the ISP, in this case) need the CNAME records or 
does the authoritative DNS also need CNAME records?

I keep thinking there will be a problem where a client configures his DNS to 
be our authoritative DNS, but then can't find the PTR because he first 
queries our DNS and we don't have the CNAME records (they're in the parent 
zone at the ISP).
