If you run the nmap
command on a server eg. nmap espn.com
or nmap -Pn espn.com
what information does that reveal to the server about you (eg. ip address or MAC address)? Does using a private vpn reduce what is revealed?
It does reveal your IP address, but not your MAC address. Using a private VPN makes the scan appear as if it is originating from the VPN's public IP address, rather than your personal public IP address.
