we just defined a Netflow V9 with Top Desitination IP and DNS lookup.
What our customer is missing: to show which country is the destination ip/dns?
Like an additional RIPE lookup after DNS lookup.
The customer migrates from competitor to PRTG and sure will be happy to use this feature also in future with PRTG ;-)
I thougt also about a possible workaround: ip/dns write to file and processing with REST API sensor connecting to RIPE search, but then i found some very simple samples about such lookups -> much more better to add this into existing Top Destination IP of PRTG.
