prevent IP registration with dynamic DNS

Hi

I have Windows 2012 server DC, witch is also client acces point for exchange 2013.

The machine has two ip addressen 172.32.2.1 and 172.32.2.11 on the same interface,  i don''t want the 172.32.2.11 to be registerd in dns. Because this ip is not reacebol from a difrent site. How can prevent registeration of this ip.

Hope some knows the answer?

With kind regards, Bas van den Dikkenberg
