How It Works
We attempt TCP connections to common ports on the target host from our Cloudflare edge server. A successful connection means the port is open; a timeout or rejection means it's closed or filtered.
Frequently Asked Questions
What is port scanning?
Port scanning probes a server's network ports to find which ones are open and accepting connections. Each port corresponds to a specific service (e.g., port 80 for HTTP, port 22 for SSH).
Is port scanning legal?
Port scanning is legal when performed on your own systems or with explicit permission. Unauthorized port scanning of systems you don't own may violate computer fraud laws in many jurisdictions.
