How to use Ping Test
The Ping tool measures whether a host is reachable and how long round-trip packets take to reach it and return, reporting latency in milliseconds and any packet loss along the way. Ping is the first command anyone reaches for when a server seems slow or unreachable, because it answers two basic questions at once: is the host up, and how good is the connection to it? Use this tool to confirm a server is online, to gauge the latency between you and it, or to spot the packet loss that points to a flaky network path.
- Enter the hostname or IP address you want to ping.
- Click Ping to send a series of echo requests.
- Read the round-trip times reported for each reply.
- Check the packet-loss percentage across the attempts.
- Compare the average latency against what you expect for the distance.
Reading latency and packet loss
Each ping reports a round-trip time — how long a small packet took to reach the host and come back. Lower is better, and the realistic floor is set by physical distance, since signals cannot beat the speed of light through fibre; a server on another continent will always show tens or hundreds of milliseconds. More telling than any single figure is consistency: times that jump around indicate jitter, and replies that never arrive show packet loss. Even a few percent loss degrades real-time uses like calls and gaming noticeably.
| Result | Meaning |
|---|---|
| Low, steady latency | Healthy connection |
| High latency | Distance or congestion |
| Variable latency (jitter) | Unstable path |
| Packet loss | Dropped packets; investigate the route |
When ping does not tell the whole story
Ping uses ICMP echo requests, and some hosts or firewalls deliberately drop or deprioritise them for security. A host that does not answer ping may therefore still be perfectly healthy and serving web traffic normally, so a non-response is not proof a site is down — it can simply mean ping is blocked. Conversely, a host can answer ping while the application on it has crashed. Ping is an excellent quick check of network reachability and latency, best paired with a service-level test like an HTTP check when you need to confirm an application is actually working.

- Detect intermittent packet loss on a path by running multiple sequential pings
- Test reachability of a remote office gateway when a VPN connection seems slow
- Verify a host is responsive before assuming a service-level failure is the cause
