IPs have the reversed lookup "assosiated" with a NS.

What do you mean with "associated"?
 
Do mean all IPs that this DNS server resolves to 
(A-Records in zone) (how do know for what zone 
the NS gives authoritative answers)?

Or just the domain name server IPs of a given 
domain name (NS records)?

What are you trying to solve?
