Port scanner

Ports: single (8080), list (22,80,443) or range (8000-8010). Leave empty to scan 24 common ports. Maximum 100 ports per scan.

Scans run from this server, so a firewall or upstream filtering may block probes. An open port only means a service is listening; it is not an assessment of vulnerabilities. Limit: 3 scans per 2 minutes per IP.

Port scanner. Attempts TCP connections to any port you specify on a public host — a single port (8080), a list (22,80,443) or a range (8000-8010). Leave the port field empty to scan 24 common service ports. An open port only shows that a connection was accepted; it does not assess the service for vulnerabilities. Examples: example.com, 1.1.1.1.
