FW: Delegating reverse DNS to a customer

Right now, I don't have a zone 250.63.in-addr.arpa (I only have the
individual zones for each class C, 224.250.63.in-addr.arpa, 225.250.63.in-addr.arpa, and so on). So I need to create the zone 250.63.in-addr.arpa? I want to make sure that won't break my other reverse DNS zones...

Thanks for your help!
