Port Scan
Examine your server’s externally accessible TCP and UDP ports.
Full scan range 1–65535 is ready.
Ports responding over UDP are shown as open. Non-responding ports may be open or filtered; their status cannot be confirmed. An ICMP rejection counts as a refused connection. Protocol-specific queries are used for DNS and NTP; other ports receive one small probe packet, which some open services do not answer.

How should I interpret the result? Open means a TCP connection was established or a UDP response received. A refused connection may indicate a closed port. A timeout or network error does not prove a port is closed.
Scan scope The single IP shown for the destination is tested from this server. Firewalls and CDNs may affect results. Service names are common port associations, not version or vulnerability detection.
