Port-scanner Common Ports
This tool scans a target IP address or domain for a predefined set of commonly used TCP and/or UDP ports—such as 21 (FTP), 22 (SSH), 80 (HTTP), and 443 (HTTPS) etc (complete list is shown below). It identifies which ports are open, closed, or filtered, helping administrators quickly assess exposed services, validate firewall rules, and detect potential vulnerabilities. Ideal for rapid security checks, network audits, and service discovery
