What Is Ping and How Does the Ping Test Work?
Ping is one of the most fundamental network diagnostic tools. It works by sending ICMP (Internet Control Message Protocol) Echo Request packets to a target host and measuring how long it takes to receive Echo Reply packets back. The round-trip time (RTT) is reported in milliseconds and indicates the latency between your network and the target. Packet loss — when some requests don't receive replies — indicates network congestion, routing problems, or an unreliable connection.
Understanding Ping Results
RTT (Round-Trip Time): The time in milliseconds for a packet to travel to the host and back. Under 20ms is excellent, 20-100ms is good, 100-300ms is acceptable for most uses, and over 300ms may cause noticeable lag. Packet Loss: The percentage of packets that didn't receive a reply. 0% is ideal; any packet loss indicates network instability. Over 5% packet loss will noticeably affect real-time applications like gaming and video calls.
When to Use an Online Ping Test
Use ping when a website or server is slow or unreachable — high latency or packet loss can point to network congestion, routing issues, or an overloaded server. Gamers use ping to check latency to game servers before playing. System administrators use it to monitor uptime and connectivity of critical infrastructure. It's also useful for comparing the speed of different DNS servers or CDN endpoints.
Why Ping Might Fail
A failed ping doesn't always mean the host is down. Many servers and firewalls are configured to block ICMP traffic for security reasons. Cloud providers like AWS often disable ping responses by default. The host may be up and serving web traffic normally but simply not responding to ping requests. If ping fails, try accessing the service directly (e.g., loading the website) or use our Port Checker to test specific ports.
For network path analysis, use our traceroute tool. For IP geolocation and ISP details, try IP address lookup. See also What is my IP, DNS lookup, VPN detection, and our port checker.

Frequently Asked Questions About Ping Tests
What is a good ping time?
Under 20ms is excellent (usually local or nearby servers), 20-50ms is very good, 50-100ms is good for most activities, 100-200ms is acceptable for web browsing but noticeable in gaming, and over 200ms will cause noticeable lag in real-time applications.
Why is my ping so high?
High ping can be caused by: distance to the server (physical distance increases latency), network congestion on your ISP's network, Wi-Fi interference, too many devices using your connection, a slow or overloaded server, or routing issues between you and the destination.
Can I ping a website that blocks ICMP?
No — if a server blocks ICMP packets, ping will fail even if the server is online and functioning normally. In this case, use our Port Checker to test if specific ports (like 80 or 443) are open, which is a more reliable way to check if a web server is running.
Is this ping test from my location?
The online ping test runs from our server, so results reflect latency from our network to the target. To test from your own location, you can run "ping hostname" in your computer's terminal or command prompt.
