Get DNS name with IP address

[rgarci6]

Hi,

Using a firewall appliance.  In it, I can see the source and destination IP addresses.  Is there a way to the DNS name of destination site instead of only the IP addresses?

I am being asked for a report to show where a particular computer is connecting to and can see the IP address to site but need to know the name of the site.

Anyway to get this information from the appliance?

Thanks for any info you can share.

New to CP and this site.
