There are three options provided with radio buttons. Select an option as per your requirement, by clicking the radio button. The options are:
In this option, Firewall Analyzer will perform reverse NS lookup of all IP addresses automatically. This will be carried out for all the reports and only the DNS names (whichever could be resolved) will be displayed in the reports. Use this option, if you want to see only DNS names of the hosts in all your reports.
This is a default option. In this option, Firewall Analyzer will not perform reverse NS lookup of IP addresses automatically and will display the IP addresses of the source and destination that participate in the conversation through firewall. If you want DNS names to be displayed for the hosts for a particular report, you can use the Resolve DNS link in the report. In each of the individual reports Resolve DNS link has been provided on top. Clicking this link enables DNS resolution for all the IP Addresses of the unresolved hosts present in the current report. The status of DNS Resolution depends on the default DNS lookup time, within which Firewall Analyzer will try to resolve the IP Address. Use this option, if you want to see DNS names of the hosts only in particular reports.
|Note:||If DNS Resolution is in progress for any other Firewall Analyzer user, the subsequent user will see the message "Please wait, DNS Resolution in progress for another user" when Resolve DNS link is clicked. Once the DNS Resolution is complete for the first user, the DNS Resolution for the subsequent user will begin automatically.|
In this option, Firewall Analyzer will display only the IP addresses of the source and destination that participate in the conversation through firewall. If you select this option, Resolve DNS option will not be available for any of the reports. Use this option, if you want to see only IP addresses of the hosts in all your reports.
|Note:||Firewall Analyzer will resolve all the IP Addresses into DNS names which are resolved by the 'nslookup' command from the machine where the product is installed.|
