Welcome to SU. Can you please elaborate on what the command do? This is my quick solution. It tells you what type of device is connected at each ip address: netstat -r.

This shows the test failing at hop 5, and continuing to fail all the way to hop 30 the default max hops for the trace route tool this means that hop 5 is unresponsive and not responding, or forwarding traffic for subsequent hops. And use Comments to let me know more. Under attack? Technically speaking, netstat -a dumps a list of current network connections. To view the IP address of a wired connection, select Ethernet on the left menu pane and select your network connection, your IP address will appear next to "IPv4 Address". Note : A result like this does not always mean the device is not online or working correctly.

The program reports errors, packet loss, and a statistical summary of the results.
In the following examples, the Ping command was used to check the connection to device A ping result, where the target device is not responding, or there is a connection issue, will look like this:. Note : A result like this does not always mean the device is not online or working correctly.
Many devices have ICMP ping responses disabled for security or service reasons.
So even if they are up and running it will appear as if they are unreachable. Unfortunately, a sample set of four pings is not suitable for detecting packet loss, so we need to run a longer test. This will ping the target times, and fill the screen with every ping sent.
We don't need to view every ping, just the final result, which will look like this:. As you can see in this test we dropped two packets but, due to the large sample size, this is negligible and is well within working parameters. We judge packet loss on a case by case basis. If significant loss is seen, we require some further testing using either PathPing or the MTR utility.
MTR probes routers on the route path by limiting the number of hops that individual packets may traverse, and listening to responses of their expiry. It will regularly repeat this process, usually once per second, and keep track of the response times of the hops along the path.
Please check the name and try again. If the end user is able to ping an IP address, but can't ping a domain name, such as bbc. This network utility is a more advanced version of the Ping tool, which performs a ping to each hop along the route to the destination unlike Ping, which just pings from the originating device to the destination device. It is extremely useful in diagnosing packet loss, and can help with diagnosing slow speed faults. The advantages of PathPing over Ping and Traceroute are that each node is pinged as the result of a single command, and that the behaviour of nodes is studied over an extended time period, rather than the default ping sample of four messages, or default traceroute single route trace.
The disadvantage is that it takes a total of 25 seconds per hop to show the PathPing statistics. In the following examples, the PathPing command was used to check the connection to device In the example, there were five hops along the route from the origin, At each hop, packets were sent and no packets lost.
The example illustrates some of the different results you might encounter. Look at each of the hop results, and what they signify. In the example, we will focus on hops 1, 3, 4, and 9. A result showing loss from the first hop indicates the likely cause to be the originating end user's router, and would be reflected with the IP address of the router such as In this instance, check, and if necessary replace, the router, then retest.
If the loss is evident from a hop after the originating router most likely hop 2 onwards , then the issue should be raised to the service provider. No packets have been dropped on hop 3, but it does have an abnormally high ping response time of ms. This could indicate that the hardware on that hop is not performing correctly, and this may be causing high response times and slow speeds.
