Check if an IP address or hostname is reachable online. Simulates a ping using HTTP probing and DNS resolution to report reachability and response time.
Ping sends ICMP Echo Request packets to a target host and measures the round-trip time (RTT) for each response. It is the most basic network diagnostic tool, used to verify that a host is reachable and to estimate latency between your location and the target server.
Round-trip time measured in milliseconds. Under 20 ms is excellent; 20–100 ms is typical for intercontinental routes; over 200 ms indicates high latency.
If some pings time out it indicates packet loss — usually caused by congestion, firewalls, or network instability along the route.
Some servers and firewalls block ICMP Echo Requests. A non-response does not always mean the host is offline — it may simply block ping.
A server-side ping test reaches targets that may be blocked from your local network, and removes your own ISP's latency from the measurement.
The target host either doesn't exist, has gone offline, or has a firewall rule dropping ICMP. Try pinging a well-known public IP like 8.8.8.8 (Google DNS) to rule out local connectivity issues.
For gaming and real-time applications, under 50 ms is excellent. For general web browsing any latency under 200 ms is acceptable. Over 500 ms will cause noticeable lag.
