When the Notify option is enabled, a master DNS server sends messages to slave
servers informing them that the zone has changed. After a slave receives a notify
message, it requests a zone transfer from the master. The Notify and
Notify Additional Servers deployment options can be set at the following
levels:
- Configuration
- Server Group
- Server
- View
- Zone
- IP block
- IP network
When you deploy a zone that has been assigned a Master deployment role and at least one Slave deployment role, the Notify setting is automatically set to Automatically Notify servers listed on the Name Servers tab. In this case, Address Manager uses the deployment roles to determine these settings and does not require you to manually configure the Notify and Notify Additional Servers options.
To enable the Notify option:
After you have added the Notify option, you can add the Notify Additional
Servers option if you want the master server to notify specific slave
servers.
