Is it illegal to scan websites with Nmap?
Network probing or port scanning tools are only permitted when used in conjunction with a residential home network, or if explicitly authorized by the destination host and/or network. Unauthorized port scanning, for any reason, is strictly prohibited.
Can you Nmap a hostname?
For this, Nmap supports CIDR-style addressing. You can append / <numbits> to an IP address or hostname and Nmap will scan every IP address for which the first <numbits> are the same as for the reference IP or hostname given. For example, 192.168. 10.0/24 would scan the 256 hosts between 192.168.
Can you use Nmap with VPN?
Nmap only supports ethernet interfaces (including most 802.11 wireless cards and many VPN clients) for raw packet scans.
Can Nmap be used maliciously?
Nmap can be used by hackers to gain access to uncontrolled ports on a system. All a hacker would need to do to successfully get into a targeted system would be to run Nmap on that system, look for vulnerabilities, and figure out how to exploit them. Hackers aren't the only people who use the software platform, however.
