Dear Mukund, 

Many thanks for coming back.

In my zone configuration I have an “allow-update” statement. 
Here I define all networks which are allowed to dynamically update the DNS entries. 

But my zone contains other IP addresses too. Not only those of the PCs.
These are static names/addresses which are seldom changed. 

And of course the complete zone is a dynamic zone. 

And I don’t wont that this static names can by changed by someone out of an IP range, where it is allowed.
I didn’t find any hint to block certain IP ranges to be updated within a dynamic zone. 

Hopefully this explains my question a little bit better.
