Tool Overview

This tool tests whether a host is reachable and measures how long it takes to get a response. You enter a domain or an IP address and choose how many samples to send. The tool sends lightweight web requests to the host and records the round-trip time for each. It then shows average latency, packet loss, jitter, and peak latency, plus a short explanation of what the result means.

When a site or server is slow or unreachable you want to know if the problem is the host or your connection. Browsers cannot send raw network ping packets. This tool uses web requests instead. It sends several requests to the host, measures the time for each, and computes loss and jitter. You see at a glance whether the host is reachable and how stable the response times are. You can stop the test early or run an optional AI diagnosis for a short written summary.

The tool is for developers, support staff, and anyone who needs to check connectivity or latency. You can use it with little experience. You type a domain or IP, click Run Ping, and read the results. Technical users can change the number of samples and use the chart and the AI diagnosis to dig deeper.

Background & Concept Explanation

Connectivity means whether your device can reach another host on the network. Latency is how long it takes for a request to go to the host and for a response to come back. That time is often called round-trip time or RTT. Packet loss is the share of requests that fail or time out. Jitter is how much the latency varies from one request to the next. High jitter can make video calls or games feel unstable. A related operation involves referencing the ASCII chart as part of a similar workflow.

Classic ping uses ICMP packets. Browsers cannot send ICMP. This tool uses web requests instead. It sends HTTP requests to the host and measures the time from when the request is sent until the browser gets a response. So it tests whether the host responds to web traffic and how fast that response is. It does not test raw network ping or show TTL. The result still tells you if the host is reachable and how the response times look.

Some hosts block or rate-limit web requests. If every request fails or times out the tool will show the host as unreachable. That can mean the host is down, your connection is broken, or the host is blocking the type of request the tool sends. You can try another host or another network to narrow it down. The tool also shows a short explanation and advice based on the result (e.g. intermittent connection, high jitter, or healthy).

Running many requests in a row gives a better picture than a single request. You choose 10, 30, or 50 samples. The tool sends each request, waits for the response or a timeout, then waits a short delay before the next one. You can stop the test at any time. The stats are computed from the samples collected so far. For adjacent tasks, looking up the ASCII table addresses a complementary step.

Key Features

• Target host input. You enter a domain (e.g. example.com) or an IPv4 address (e.g. 8.8.8.8). The tool checks that the value looks like a valid domain or IP. It then sends requests to that host using HTTPS. This lets you test any host that accepts web traffic.
• Sample count. You choose 10, 30, or 50 requests. The tool sends that many requests one after another (with a short delay between each). More samples give a more stable view of latency and loss but take longer. This lets you balance speed and accuracy.
• Run and stop. You click Run Ping to start the test. The tool sends the requests and updates the results as each one finishes. You can click Stop to cancel. The stats shown are for the samples collected before the stop. This lets you abort a long test if you have enough data.
• Results: average RTT, packet loss, jitter, peak latency. After the test the tool shows the average round-trip time in milliseconds, the percentage of requests that failed or timed out, the jitter (average variation between successive response times), and the peak (maximum) latency. You use these to see if the host is reachable and how stable the connection is.
• Status badge. The tool labels the result as Reachable, Unreachable, or Intermittent. Reachable means no loss and stable responses. Unreachable means no successful responses or all timed out. Intermittent means some loss. This gives you a quick read without looking at the numbers.
• Real-time ticker. While the test runs and after it finishes you see a row of small boxes for the last several results. Each box shows the response time in milliseconds or a mark for timeout or error. This lets you see the pattern of successes and failures at a glance.
• Latency chart. A line chart plots each sample number and its response time. You see how latency changed over the test. This helps you spot spikes or a gradual increase.
• Connection insight. The tool shows a short headline, description, and advice based on the result. For example it may say the host is unreachable, connection is intermittent, high jitter, high latency, or connection is healthy, and suggest what to try next. This helps you interpret the numbers.
• Copy summary. You can copy a one-line summary (average latency and loss) to the clipboard. Useful when you want to paste the result into a ticket or chat.
• Optional AI diagnosis. After a test you can click AI Diagnosis. The tool sends the target, stats, and result history to a backend and returns a short written diagnosis. This is optional and needs the network. Use it for an extra interpretation of the result.

Common Use Cases

Checking if a site is up. You cannot open a website. You enter the domain and run 10 pings. If the tool shows unreachable and 100% loss the host may be down or blocking requests. If it shows reachable with low latency the host is responding; the issue may be with your browser or the specific page.

Measuring latency to a server. You want to see how fast responses are from a given host. You enter the domain or IP and run 30 or 50 samples. You look at the average RTT and the chart. High average or big spikes in the chart suggest distance or congestion.

Diagnosing intermittent issues. A connection works sometimes and fails other times. You run a test with 50 samples. If the tool shows intermittent and some packet loss you see the pattern in the ticker and chart. The connection insight suggests causes (e.g. Wi-Fi interference) and what to try (e.g. Ethernet, move closer to the router). When working with related formats, calculating subnet masks can be a useful part of the process.

Comparing before and after a change. You change network or router settings. You run the same test to the same host before and after. You compare average RTT, loss, and jitter to see if the change helped.

Sharing a quick result. You run a test and copy the summary (average ms and loss %). You paste it into a support ticket or chat so someone else can see the result without running the tool.

How to Use This Tool (Step-by-Step)

1. Open the tool. You will see a target host field, a samples dropdown, and a Run Ping button.
2. Enter the host. Type a domain (e.g. google.com) or an IPv4 address (e.g. 8.8.8.8). The tool will add https:// if you do not type a protocol. Leave out http or https; the tool uses HTTPS.
3. Choose the number of samples. Select 10, 30, or 50 pings. More samples take longer but give a more stable view of latency and loss.
4. Click Run Ping. The tool sends the requests and updates the ticker and results as each one finishes. Wait for the test to complete or click Stop to cancel.
5. Read the results. You will see Average RTT, Packet Loss, Jitter, and Peak Latency, plus a status badge (Reachable, Unreachable, or Intermittent). Use the connection insight section to read the short explanation and advice.
6. Look at the ticker and chart. The ticker shows the last several results (time in ms or a mark for failure). The chart plots latency over the test. Use them to see patterns and spikes.
7. Copy the summary if needed. Click Copy to put the one-line summary (average ms and loss %) on your clipboard. Paste it where you need it.
8. Use AI Diagnosis if you want. After the test click AI Diagnosis. Wait for the text. Read the diagnosis and use the Clear button to remove it. This step is optional.

Calculations & Logic

The tool sends web requests to the host. For each request it records the start time, sends the request, and when the response is received (or the request times out) it records the end time. The round-trip time for that sample is the difference in milliseconds. If the request fails or times out the sample is counted as a failure and no RTT is stored for that sample for the average. In some workflows, testing for packet loss is a relevant follow-up operation.

Packet loss is the number of failed or timed-out requests divided by the total number of requests, expressed as a percentage. So if 2 out of 10 requests fail the loss is 20%.

Average RTT is the sum of all successful response times divided by the number of successful responses. Minimum and maximum RTT are the smallest and largest among successful responses. The tool displays the average and the maximum (peak latency). Jitter is the average of the absolute differences between each pair of successive successful response times. So if the times were 10, 15, 12 ms the differences are 5 and 3, and the jitter is 4 ms. Jitter is only computed when there are at least two successful responses.

Reachable means at least one successful response and 0% loss. Unreachable means no successful responses or 100% loss. Intermittent means there is some loss but not 100%. The connection insight text is chosen from rules based on status, loss, jitter, and average latency (e.g. high jitter if jitter is above a threshold, high latency if average is above a threshold). For related processing needs, testing responsive layouts handles a complementary task.

Tips, Limitations & Best Practices

The tool uses web requests, not ICMP ping. It tests whether the host responds to HTTPS requests and how long that takes. It does not show TTL or raw network-level ping. Some hosts block or rate-limit web requests; if every request fails the tool will show unreachable even if the host is up for other traffic. Try a well-known public host (e.g. a search engine) to verify the tool works on your network.

Each request has a timeout (a few seconds). Slow hosts may time out often and show high loss. That can mean the host is slow or overloaded, not that it is down. Use the average RTT and the chart to see if some requests succeed; if they do, the host is reachable but slow.

Results depend on your network and the path between you and the host. Running the same test from a different network or at a different time can give different results. Use the tool as a snapshot of connectivity and latency from your current location.

You can stop the test early. The stats and chart are based only on the samples collected before the stop. For a quick check a few samples may be enough; for a stable estimate use 30 or 50 and let the test finish.

The AI diagnosis is optional and runs on a backend. It needs network access and may be subject to usage limits. If it fails you still have the numeric results and the connection insight. Use the AI for an extra written summary, not as the only source of truth.
