What does ping measure?

Ping measures whether a host is reachable and how long a round trip takes. It sends ICMP echo requests and records the reply time, reporting packet loss and the minimum, average and maximum round-trip latency in milliseconds.

Where are the ping requests sent from?

From our servers in the EU, not from your computer. The result reflects reachability and latency between European infrastructure and the target, which is why the numbers differ from a ping you run on your own machine.

Why is a host showing 100% packet loss even though it works?

Many hosts and firewalls block ICMP while still accepting normal traffic. Total ping loss can simply mean echo requests are filtered, so confirm with a port-level test before concluding the host is down.

Can I ping a hostname instead of an IP address?

Yes. Enter a hostname and it is resolved to an IPv4 address first, then pinged; the resolved IP is shown with the results. To test IPv6 targets, use the separate Ping IPv6 tool.

Why can't I ping a private or local IP address?

Private ranges such as 192.168.x.x or 10.x.x.x are only reachable inside their own network. Since this test runs from our EU servers, those addresses are unreachable and are rejected.

Ping IPv4

Send ICMP echo requests to any IPv4 address or hostname from our European servers and read back packet loss and round-trip latency, minimum, average and maximum.

About Ping IPv4

Ping is the simplest reachability test on the internet: it sends an ICMP echo request to a host and times how long the echo reply takes to come back. This tool sends four requests to the target from our EU-based servers, then reports what happened - how many packets were transmitted and received, the packet-loss percentage, and the round-trip time broken down into minimum, average and maximum. Each individual reply also shows its TTL and timing, so you can see variability between packets rather than just an average.

Because the packets originate on our infrastructure rather than your own machine, this is a server-side view of reachability from Europe. That makes it useful in two situations: confirming that a host is actually up when your local network or ISP cannot reach it, and measuring how quickly a service responds to European users. If you enter a hostname, it is first resolved to an IPv4 address and the ping is sent to that address; the resolved IP is shown alongside the results.

A word on interpreting the numbers. Latency is dominated by physical distance and network path, so a server on another continent will show a higher average than a nearby one, and that is normal. Any packet loss above zero on a stable path is worth investigating, but 100% loss does not automatically mean the host is down - many servers and firewalls deliberately drop ICMP while still serving traffic on their real ports. For those cases a port-level connectivity test is a better signal than ping alone.

The tool accepts only public, resolvable hosts; private and internal addresses are rejected, since they are unreachable from and meaningless to an external vantage point.

How to use it

1Enter an IPv4 address (such as 9.9.9.9) or a hostname (such as example.eu) to test.
2Run the test to send four ICMP echo requests from our European servers.
3Check the packet-loss percentage first - 0% means every request got a reply.
4Read the min/avg/max round-trip times to judge latency and how much it fluctuates.
5Compare the per-packet TTL and timing values to spot an unstable or congested path.

Common use cases

-Confirm a server is reachable from outside your own network when you suspect a local connectivity problem.
-Measure the latency your European users experience when reaching a host or service.
-Spot packet loss on a path that is causing slow or dropped connections.
-Quickly verify that a newly provisioned IPv4 host is online and responding.
-Get an independent, external reachability check to include in an incident report or ticket.
