Ping Tool

What is Ping? Ping measures network connectivity and round-trip time (RTT) between your device and a target host. This tool uses ICMP (real ping) as the primary method.

ICMP Ping: Standard network ping protocol. Provides accurate RTT and TTL values. Requires CAP_NET_RAW capability on the server. This is the only method available for security reasons (TCP and HTTP ping have been removed to prevent potential abuse).

OS Detection: Different operating systems use different initial TTL (Time-To-Live) values: Linux/Unix typically uses 64, Windows uses 128, and network devices use 255. The number of network hops can be estimated from TTL reduction.

Connection Quality: Score is calculated based on latency, jitter (variation), and packet loss. Scores: 90-100 = Excellent, 75-89 = Good, 50-74 = Fair, <50 = Poor.

Jitter: Measures latency variation between ping attempts. Low jitter (<5ms) indicates stable connection, high jitter (>30ms) suggests unstable or congested network.

Use Cases: Network troubleshooting, latency testing, connection quality monitoring, CDN performance analysis, and basic reachability checks.
