You might also use DNAME records if you have a number of multihomed appliances whose IP addresses must be mapped to a single set of domain names. An example of this is shown in Figure 20.6.
Note: If you specify a subdomain in the Domain Name field when configuring a DNAME record, and the subdomain is also a subzone, the DNAME record appears in the list view for the subzone, not in the list view for the parent zone that was selected when adding it.
The DNS client then examines the fields in the NAPTR record as follows:
- Perform a global search to retrieve the record you want to delete.
From the Data Management tab, select the DNS tab, click the Zones tab-> dns_view -> zone -> host_record or resource_record.
- Select the record and click the Delete icon.
- In the Delete Confirmation dialog box, select Yes to delete or No to cancel.
- Optionally, if the Enable PTR record removal for A/AAAA records option is selected and if you try to delete an A or AAAA record, the appliance displays the Delete Confirmation (A or AAAA Record) dialog box to confirm whether you want to remove the corresponding PTR record that was automatically generated while creating the A or AAAA record. In the Delete Confirmation dialog box, select the Remove associated PTR resource record(s) check box and click Yes to delete the associated PTR record or click No to cancel. For information about enabling this option, see Deleting PTR Records associated with A or AAAA Records.
You can also schedule the deletion for a later time. Click Schedule Deletion and in the Schedule Change panel, enter a date, time, and time zone. For information, see Scheduling Deletions.
