DHCP zone groups are container objects for DHCP zone declarations. You use forward and reverse DHCP zone declarations to configure TSIG or GSS-TSIG signing of Dynamic DNS updates.
To configure a DHCP zone group, you simply specify a name for the container. After creating the DHCP zone group, you assign the group one or more deployment servers. Deployment servers are the servers to which Address Manager deploys the forward and reverse DHCP zones within the group.
To create a forward DHCP zone, you specify a DNS zone, the primary DNS server IP address, and an optional TSIG key or GSS-TSIG DNS service principal. The DNS zone may be a zone under Address Manager control, or it may be a zone outside of your network that you do not manage with Address Manager.
