🏓 Ping Test

Measure HTTP response latency to any URL. This tool sends HTTP requests and measures round-trip time — not ICMP ping — due to browser security restrictions.

⚠️ Browser limitation: True ICMP ping is not possible from a web browser. This tool measures HTTP response time using the Fetch API. Results may differ from command-line ping. CORS restrictions may affect some targets — try httpbin.org/get for a CORS-friendly endpoint.

🔒 About CORS

Browsers enforce CORS (Cross-Origin Resource Sharing) which may block reading response details from some servers. In no-cors mode, the request still completes and timing is measured, but the HTTP status code will show as "opaque."

For full status codes, use CORS-enabled endpoints like httpbin.org/get.

What is a Ping Test?

A ping test measures the time it takes for a small data packet to travel from your device to a remote server and return. This round-trip time, called latency, is measured in milliseconds (ms). Ping tests help diagnose network issues, compare server response times, and verify that a host is reachable.

Traditional ping uses ICMP (Internet Control Message Protocol) packets at the network layer. This browser-based tool uses HTTP requests instead, since browsers cannot send ICMP packets for security reasons. The HTTP round-trip time is a practical proxy for measuring server responsiveness and network latency.

HTTP Ping vs ICMP Ping

ICMP ping (the ping command in your terminal) sends lightweight echo-request packets at the network layer. It measures raw network latency with minimal overhead, and is supported by virtually all networked devices. However, some servers and firewalls block ICMP traffic.

HTTP ping sends an HTTP request (typically HEAD or GET) to a web server. It measures the full round-trip including DNS resolution, TCP handshake, TLS negotiation, and server processing time. HTTP latency is typically higher than ICMP latency because of this additional overhead, but it more closely reflects the real-world experience of loading a web page.

FAQ: What is ping?

Ping is a network utility that tests connectivity between two devices by sending a small packet and waiting for a response. The name comes from sonar — like a submarine sending out a sound pulse ("ping") and listening for the echo. The time between sending and receiving is the latency.

FAQ: What is a good ping latency?

Under 50 ms is excellent for gaming and real-time applications. Under 100 ms is very good for general browsing. 100-200 ms is acceptable. Over 300 ms may cause noticeable delays, and over 500 ms usually indicates a connectivity problem.

FAQ: Why can't I ping from a browser?

Web browsers run in a sandboxed environment that restricts access to low-level network protocols like ICMP. This is a security measure — allowing raw socket access from a web page could enable denial-of-service attacks and network scanning. Browser-based tools use HTTP requests as an alternative.

FAQ: What is ICMP?

ICMP (Internet Control Message Protocol) is a supporting protocol in the Internet protocol suite. It is used by network devices to send error messages (e.g., "destination unreachable") and operational queries (e.g., ping echo requests). ICMP operates at the network layer, alongside IP, rather than at the transport layer like TCP or UDP.

FAQ: What causes high latency?

Common causes include physical distance between client and server, network congestion during peak hours, overloaded or misconfigured servers, inefficient routing paths, ISP throttling, Wi-Fi interference, and insufficient bandwidth. Using a CDN, choosing geographically closer servers, and using wired connections can all help reduce latency.
