Thanks for the software, i will look at it.
There is no web server installed on the slaves servers being used for the netscan
My ISP - CH :
ISPConfig Master only Web enabled
SQL Server 1
Mail Server 1
DNS Server 1
DNS Server 2
OVH - FR :
Web server 2 (currently not reported by hetzner)
SQL Server 2
DNS Server 3
DNS Server 4
Only SQL and DNS Server #3 & #4 hosted by OVH was used for the netscan. Like said above, these VPS does not have any web server installed on them.
Each VPS have their own public IP addresses.
