DDNS - limitation and excluding updates from certain networks

[MAYER Hans]

Dear All,

My environment: We are using the latest version of BIND and DHCP from ISC. Our workstations ( mostly Windows and some Mac ) are in certain networks. Only these networks are allowed to do dynamic DNS updates. So when a PC is switched on its IPv4, IPv4 reverse, IPv6 and reverse is registered. 

So far everything works well. 

Is there a way to configure, that names which are registered in other networks, are not allowed to be updated ? 


Kind regards 
Hans
