The Tools tab provides the Ping and Traceroute utilities
Ping
Ping is used to test whether or not a host on an IP network can be reached and to measure
the round-trip time for messages sent from the originating host to a destination such as an

To run Ping, select Ping from the Tools pane and enter the IP address of the destination. The
results of the ping is statistical summary of the response packet received and the round-trip
time taken for the packet in the message to be sent and received. For example:

The destination IP is pinged ten times.
