Mac OS X OD Master registers ALL interfaces with DNS

Hello, I'm having a problem where my Mac OS X OD master is registering all of its interfaces with my Windows AD DNS. This is bad, because one interface is on a private metadata (XSAN) network, and is not accessible from the production network. Therefore I have clients trying to talk to my OD master on an interface that's not available. Does anyone know how to stop my OD master from registering the private interface to the Windows AD DNS? Thanks, -Josh
