![]() ![]() To get reliable ping data it is necessary to ping from different global locations. Type CTRL-C to end the pinging, or close the command window. To continuously ping with Windows, use the -t switch. This is particularly useful when installing, replacing, or removing network equipment. If the pings stop coming back successful, then the change has broken the previously functioning network. This can be useful for many situations, including ensuring the remote host stays reachable, or to see when connectivity is lost.įor example, an administrator can set a system to ping a remote host while making adjustments to wiring, or testing network equipment. Keeping Pinging!Īnother trick for troubleshooting with ping is to set a continuous ping. If that fails, the network is not running properly on the system. ![]() To ping the loopback address, simply ping 127.0.0.1. It is not only easy to remember, it is very likely to be up and running at any given time.įinally, pinging the loopback address ensures that the network stack is functioning and properly initialized on the system itself. To test connectivity to the internet, some administrators ping 8.8.8.8, which is Google’s primary DNS server. If the gateway does not ping, then either the problem is with the gateway itself, or on the route to the gateway. If the gateway pings, that means the local portion of the network is functioning and the problem lies beyond. ![]() On many computers the default gateway can be determined by examining the IP configuration. The first key point to ping is the gateway. To get a better idea about where the network issue is, an administrator can ping key parts of the network infrastructure like the router. Knowing where the problem is, is much better. Knowing that your network connection isn’t working properly or your internet is down is one thing. How To Pin Point Network Issues With Ping However, if some pings do come back, then at least the network configuration is functional. While all four of our pings came back good, missing pings suggest trouble on the network. While there is no “good” time for a ping to take, a time that is significantly higher than usual, or significantly higher than other hosts on the same network could indicate issues as well. A wide variation might suggest that there is a connection issue, perhaps network congestion. Also listed is the time that the pings took, in this case a minimum of 13 milliseconds (ms), and a maximum of 23 ms. In the above example, there were four pings sent and replies received. In the example above, if I can ping the IP, but cannot ping the URL, then my problem is with resolving the name, perhaps a misconfigured DNS server. If you can ping a host by its IP address, but not by the name, then the problem is with name resolution. Which brings us to another troubleshooting step. Ping actually sends requests to an IP address. In this case, maybe the problem is with the webserver configuration instead. Those four replies show that the network and internet connection is good and that the server is reachable. To use ping, just type ping and then the host you are trying to reach.įor example, if you are having trouble connecting to a website, you could try and ping the URL of that website (see example below). If your ping is returned, then the network is working, and any issue you are having lies somewhere else. Remember, not all devices are configured to respond to a ping request, so be sure that what you are trying to ping can even respond. The first step in any connectivity troubleshooting with ping is to simply try and ping the remote host. A successful ping results in a response from the computer that was pinged back to the originating computer. The ping command sends ICMP echo request packets over the network to a specific device. I Ping is a command-line utility, available on virtually any operating system with network connectivity, that acts as a test to see if a networked device is reachable.
