The "Resolve Hostname" feature can resolve the ip address in a log entry to the corresponding hostname using the address objects configured on the firewall or by doing a DNS lookup.
When this box is checked, the firewall tries to resolve the ip addresses in the logs to the corresponding hostnames.
When the checkbox is selected, the device will first check if there is a corresponding address object configured. If found, it will display the same. If an address object is not configured on the device, the device will send out a DNS request for the PTR record of the ip address.
Note: When an address object is configured on the device for a particular address and when there also is an entry for this address in the DNS server, the "Resolve Hostname" would resolve the address to the configured address object.
I couldn't find any documentation about who is doing the DNS lookup when working with Panorama. Is it the firewall or the Panorama.
Anyway, when I use this feature in Panorama, it does not display the corresponding object configured with the same IP.
