Ping is a tool that lets you verify that a particular IP address exists and can accept requests by sending an Internet Control Message Protocol (ICMP) Echo request. Ping is used diagnostically to ensure that the host computer you are trying to reach is actually operating. If, for example, you can't ping a host, then you will be unable to use File Transfer Protocol (FTP) to send files to that host. Ping can also be used with a host that is operating to see how long it takes to get a response back. If a host computer is operating, it normally sends back an Echo reply message.


This tool can work in two modes. If you uncheck the Ending IP address box, it will ping just one IP address, and each ping will be shown on a separate line. If you check the Ending IP address box, it will ping a range of IP addresses, and each address will be shown on a separate line. In the latter mode, the Response Time column will display minimum, average, and maximum times separated by slashes.

To use this tool, enter an IP address or hostname and click Start. The following options are available:

· Pkts. – sets the number of packets to be sent to the remote host.
· Delay– sets the interval (in milliseconds) between pings.
· Pkt. size – sets the size (in bytes) of the data portion of the ICMP packet.
· Timeout – sets the maximum time (in seconds) Ping will wait for the response from a host.
· DNS resolving – check this box if you want TraceRoute to resolve IP addresses to hostnames.
· Don't fragment – sets the Don't fragment flag in the packet.
· Tasks – sets the number of simultaneous tasks when pinging a range of IP addresses. It is recommended to keep this number low if your PC doesn't have ample RAM, as a high number of parallel tasks might exhaust your system resources.

Right-clicking on the window brings up a menu with the following commands:

· Send To – sends the selected IP address to other tools or to SmartWhois.
· Copy Results – copies the Ping table to the clipboard.
· Save – saves the Ping table to a file.
