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. |
