Some speed test services let you choose a server, others give you no choice. You will encounter some variability when running different tests on the same service, particularly for providers like which use different servers depending on where you are. Your internet service provider might even have its own speed test service. There are plenty of internet speed test services to choose from, with, , and CloudFlare being some of the most well-known options. So how can you know for sure, and does it matter? Different Speed Tests Report Different Results That address is always 127.0.0.1, and pinging it successfully lets you know that the network adapter on your computer (and the networking software in your OS) is working properly.Do you know how fast your internet connection is? Depending on which service you use, you could get vastly different results. If you can't successfully ping your router, but your router appears to be turned on and working, you can try pinging what's known as a loopback address. Ping your loopback address (127.0.0.1).A successful response lets you know that your local network is working okay, and that the problem reaching the internet location is somewhere out of your control. If you can't successfully ping an internet location, you can then try pinging your router. Ping your router to see if you can reach it.The ping tool shows you right at the top the IP address it's working with. If you want know the IP address for a particular URL, you can ping the URL. And if you're interested in exploring those routes further, you can use another networking tool named tracert to do just that. If you get a successful response, you know that all the networking devices between you and that destination are working, including the network adapter in your computer, your router, and whatever devices exist on the internet between your router and the destination. Ping a URL (like or IP address to see if you can reach an internet destination.Now that you know how to use the command, here are some interesting things you can do with it: The time it takes packets to return to you can help you identify a slow connection, or if you're experiencing packet loss. This can help you determine if a network problem is somewhere on your local network, or somewhere beyond. You can test whether your computer can reach another device - like your router - on your local network, or whether it can reach a device on the Internet. When it gets the response, the ping tool shows you how long each packet took to make the round trip - or tells you there was no reply. Your computer sends several packets of information out to that device, and then waits for a response. You issue the ping command along with a specific URL or IP address. On a computer network, a ping tool is built into most operating systems that works in much the same way. Ping comes from a term used in sonar technology that sends out pulses of sound, and then listens for the echo to return. It's a handy tool that you can use to quickly test various points of your network. The ping command sends packets of data to a specific IP address on a network, and then lets you know how long it took to transmit that data and get a response.
