Ping

Sends out an echo request to a specific computer on the network. It can be used to check communication links or to check whether the specific host exists or is running.

WARNING: If you run this tool on your own IP address, your firewall or intrusion detection system may inform you on a "port scan" or "network attack" originating from qs153.pair.com (216.92.131.153). This is the return traffic from the ping that you initiated rather than an intrusion attempt. Please keep this in mind when you analyze your firewall logs and think twice before e-mailing the network administrator, as we receive frequent complaints from newbies who think that someone is trying to break into their PCs. Thank you.
