On ping command how to see internet highest speed would ping result lime

**Short answer**
The standard `ping` command does **not** report your Internet connection’s “highest speed.” `ping` only measures latency (how long a small packet takes to make a round-trip), not bandwidth (how much data you can move per second). To learn your true upload/download speed you need a throughput-testing tool such as `iperf`, `speedtest-cli`, or your ISP’s web speed test.

## Why `ping` can’t show bandwidth

| Metric | What `ping` really tells you | What it does **not** tell you |
|-------------------|------------------------------|--------------------------------|
| `time=` (RTT) | Round-trip latency in ms | Transfer rate (Mbps / MBps) |
| `ttl=` | Remaining hop limit | Quality of service |
| Packet loss | Reliability of the path | Maximum sustainable throughput |

*Bandwidth* (speed) is the volume of data you can push through a link per unit time, whereas *latency* is the delay before the first bit arrives. A link can have:

* Low latency but low bandwidth (e.g., fiber to old Wi-Fi 802.11b router)
* High latency but high bandwidth (e.g., satellite)

Because `ping` sends tiny ICMP packets (typically 56 bytes), even a 1 Gbps fiber and a 10 Mbps DSL can answer in the same 5–10 ms. You simply cannot infer the link’s “highest speed” from that number.

## Interpreting the `ping` output you do see

64 bytes from 8.8.8.8: icmp_seq=1 ttl=117 time=23.4 ms

* `64 bytes` – total ICMP payload size returned
* `icmp_seq` – sequence number so you can spot missing replies
* `ttl` – Time-To-Live left when the packet arrived (helps diagnose routing loops)
* `time` – round-trip latency in milliseconds

After you stop `ping` (`Ctrl-C`), you’ll see a summary such as:

--- 8.8.8.8 ping statistics ---
5 packets transmitted, 5 received, 0% packet loss
rtt min/avg/max/mdev = 22.8/23.1/23.7/0.3 ms

Those last four numbers are the minimum, average, maximum, and standard deviation (mdev) of your latency samples—not speeds.

---

## If you still want a rough “speed” from `ping`… (why it’s misleading)

People sometimes multiply the packet size by 8 (bits) and divide by the reported time to get a theoretical throughput. Example:

• 56 bytes × 8 = 448 bits
• `time=20 ms` ⇒ 0.020 s
• 448 bits / 0.020 s ≈ **22.4 kbps**

That looks absurdly slow because the packet is so small. The network finishes it in microseconds; the rest of the 20 ms is propagation + processing delay. Hence the “speed” figure is meaningless.

## How to properly check bandwidth

Tool (CLI) | What it measures | Quick use example
-------------------- | --------------------------- | ------------------------------
`speedtest-cli` | Download & upload Mbps | `speedtest`
`iperf3` | Raw TCP/UDP throughput | `iperf3 -s` (server) / `iperf3 -c `
`nperf`, `fast.com` | Browsers, video throughput | Visit in a web browser

These utilities send large continuous streams of data, saturating the link long enough to reveal its realistic maximum speed.

### Takeaway

1. Use `ping` to gauge **latency** and packet loss.
2. Use `iperf`, `speedtest-cli`, or a browser-based test to determine **highest Internet speed**.
3. Don’t confuse the two metrics—both matter, but they answer different questions about network quality.

Happy testing!
