the k12.pa.us domain is currently setup and running ( has been for 
years ). and I have been asked to add bethsd.org in addition to the 
k12 domain. It's not like I'm just adding a web server. They want to 
have both domain names function for the same address space ( which is 
several class C blocks ).
Where i get confused is that this is not a sub domain that is under 
the .us tree.

My problem is understanding how reverse lookups should be handled. i 
can create the the forward files with the same addresses as the k12 
domain, but then what do I do about reverse lookups. At this point I 
have been advised several times "not" to use multiple PTR records.

to me this doesn't seem logical. two domains using the same address 
space. The primary dns server will actually function as 
dns.beth.k12.pa.us and ns.bethsd.org.

-- im trying to measure twice and cut once :)
any advice you guys could give me would be helpful.
