Use the Cache Time tab of the Reverse Mapping
for Host Notebook to specify the time-to-live (TTL) value for the reverse
host, that is, the maximum number of seconds that the reverse host resource
records will be cached at a caching server. The value specified is used for a
pointer (PTR) record when the record is created.
Note:
This tab applies only to hosts in a primary domain.
The Cache Time tab has this field:
- Reverse host (PTR) cache time
- Specifies the maximum amount of time, in seconds, that the reverse
mapping, which is stored in the pointer (PTR) resource record, is to be
cached. To specify a time, you must uncheck the Use Domain Default Cache Time
check box.
- Use domain default cache time
- If a cache time is not specified, indicates that the default cache time
specified on the Domain Options tab of the Primary Domain Notebook is to be
used.
These push buttons are available on the Cache Time tab:
- OK
- Retains the configuration data in this notebook and closes the notebook.
- Cancel
- Cancels any actions taken in this notebook and closes the notebook.
