Ping
Measure HTTP response time to any host. Shows min, avg, and max latency over multiple requests.
Ping measures how quickly a host responds. This tool sends several HTTP requests to a domain or IP and reports the minimum, average, and maximum response time plus packet loss, giving a fast read on latency and availability. Because browsers can't send ICMP echo packets, it measures HTTP round-trip time rather than a classic ICMP ping.
Frequently asked questions
What is a good ping time?
Under ~100 ms feels responsive and under 30 ms is excellent. Higher values mean more delay, which matters most for real-time apps like games and calls.
Why is this different from command-line ping?
Terminal ping uses ICMP, which browsers can’t. This measures HTTP response time, which includes connection and server processing and is usually a little higher.
What does packet loss mean?
It’s the share of requests that got no reply. Consistent loss points to network trouble, an overloaded server, or filtering.
Why does latency vary between runs?
Routing, server load, and your own connection fluctuate moment to moment, so times differ across attempts.
Can I ping a host behind a firewall?
Only if it answers HTTP requests. A host that blocks or doesn’t serve HTTP appears as loss or a timeout.
