$ ping
Send 1 to 20 ICMP echo requests from this server to a public host (default 4).
About the ping tool
Ping sends ICMP echo requests to a host and measures how long each reply takes. It is the quickest way to see whether a server is reachable and how far away it is in network terms. This tool sends the packets from the 9w7.net server, not from your device, so it tells you how the host looks from a public datacenter.
How to read the results
time is the round-trip latency in milliseconds; lower is better. ttl is the remaining hop limit on the reply, which hints at the operating system and path length. Packet loss above 0% on a short test can mean congestion, a flaky link, or a host that rate-limits ICMP. mdev shows how much latency varies: a large value means jitter. If every packet is lost, the host may be down, or it may simply block ping while still serving web traffic.
FAQ
- What does a ping test tell me?
- Whether a host answers at all, the round-trip latency to it, and the percentage of packets lost on the way.
- Why does ping show 100% loss when the website works?
- Many firewalls and cloud providers drop ICMP echo requests. Try the TCP ping tool against port 443 or 80 to test the service itself.
- What is a good ping time?
- Under 30 ms is typical within a region, 80-150 ms across continents. Consistency (low mdev, no loss) matters more than the lowest value.
- Is this ping from my computer?
- No. It runs from the 9w7.net server, so it measures the path from there to the target.
