Configuring SOa resource records
The SOA resource record is a Start of Authority record that sets the version number of a DNS
zone. Typically, this record is not manipulated manually, but is automatically incremented
whenever there is a change to the zone. The version number is used to determine which zone
record is authoritative if there have been DNS zone changes in more than one location.
To update a SOA record with the DNS Manager console, follow these steps:
Open the DNS Manager console.
1.
Expand the server on which you want to create the record and then expand the Zone
you want to configure.
2.
Right-click the zone name and select Properties from the menu.

4.
Click the Start Of Authority (SOA) tab, as shown in Figure 3-24.
