Network Scan

What is network and port scanning, and how does it work?

Browsers do not allow direct port scanning for security reasons. Real network scanning requires desktop tools or authorized server-based services. In this section you will learn scanning concepts, common ports and safe usage principles.

Only scan networks you own or have permission to test. Unauthorized scanning may be illegal.
