What is the stautus of a computer? What about my site, why I cann't load it? What about my visitors? What they are seeing? Just some reasons to use ping, from your computer and from pan-Internet.com application.
A simple way to see if a comuter is working: send ping command. This can be done from your operating system, or from a web application like pan-Internet using ping application from pan Internet.
You can send ping to a IP address (example ping 127.0.0.1 is sending a ping to your own computer using loopback interface), ping to a domain (example ping pan-internet.com is sending a ping command to the server where this site is hosted); also for sending ping to your computer you can use ping localhost - this is the same as ping 127.0.0.1. The result of the ping, called response can tell to you how is your connection with the machine where you have sent ping - time that was necesary for receiving the response, the percent of lost data in this command show you how you can comunicate with that machine.
Also the ping command can be used with some parameters that will modify the behaviour of this command; on ping application you can see the complete tehnical details of this command. For example, if you need to test the behavior of a server, you can send the ping command continously, but be carefully, this can be considered a attack by the firewall and can block your connection with the server:
panInternet Ping application send pings without parameters. Just simple pings;to use parameters I recomand to you to use your windows/linux command line, from there you have a lot of options for sending ping.
