DDNS Server Administrator Help

Notify Servers Tab

Use the Notify Servers tab of the Primary Domain Notebook to specify the name servers that are to be notified when the serial number changes. The serial number identifies the current revision level of the data for this domain. For dynamic domains, the serial number is automatically incremented by the name server; for static domains, it is automatically incremented by the DDNS Server Administrator program when the configuration is saved. The default notify set is the set of secondary name servers defined for this domain on the Secondary Name Servers tab.

The Notify Servers tab has these fields and check boxes:

Notify the domain name servers listed below when the domain database serial number is updated.
When checked, indicates that you want this name server to notify the specified name servers whenever the serial number changes (indicating that the domain data has changed). This option facilitates the updating of the secondary name servers and enables them to remain more current.

IP address
Specifies the IP address (in dotted decimal notation) of a name server to add to the notify set. After typing the address, click Add.

List box
Displays the names and IP addresses of the name servers in the notify set. To remove an entry from the list box, select the entry and click Remove.

Time to wait between attempts to notify a particular server
Specifies the interval, in seconds, between successive attempts to notify a particular name server, if the attempts fail.

Number of times to attempt notifying a server
Specifies the maximum number of times that attempts are to be made to notify a particular name server if the server fails to respond.

Time to wait between notifying different servers
Specifies the interval, in seconds, between the first attempt to notify a server in the notify set and the first attempt to notify the next server in the notify set.

For dynamic domains, increment the database serial number
Specifies the conditions for updating the serial number. The serial number is updated whenever either of these conditions is met.

Note:

When setting these values, consider the volume of requests and the rate at which they are made.

n seconds after any update
Specifies the number of seconds to wait after an update before incrementing the serial number.

or after n updates are made
Specifies the number of updates to be made before incrementing the serial number.
