Please Whitelist This Site?
I know everyone hates ads. But please understand that I am providing premium content for free that takes hundreds of hours of time to research and write. I don't want to go to a pay-only model like some sites, but when more and more people block ads, I end up working for free. And I have a family to support, just like you. :)
If you like The TCP/IP Guide, please consider the download version. It's priced very economically and you can read all of it in a convenient format without ads.
If you want to use this site for free, I'd be grateful if you could add the site to the whitelist for Adblock. To do so, just open the Adblock menu and select "Disable on tcpipguide.com". Or go to the Tools menu and select "Adblock Plus Preferences...". Then click "Add Filter..." at the bottom, and add this string: "@@||tcpipguide.com^$document". Then just click OK.
Thanks for your understanding!

TCP/IP Communication Verification Utility (ping/ping6)
(Page 3 of 5)
Basic ping Use
The most basic use of the ping
command is to enter it by itself with the IP address of a host. Virtually
all implementations also allow a host name to be used, which will be
to an IP address automatically. When the
utility is invoked with no additional options, default values are used
for parameters such as what size message to send, how many messages
to be sent, how long to wait for a reply, and so on. The utility will
transmit a series of Echo messages to the host and report back
whether or not a reply was received for each; if a reply is seen, it
will also indicate how long it took for the response to be received.
When the program is done, it will provide a statistical summary showing
what percentage of the Echo messages received a reply, and the
average amount of time for them to be received.
shows an example using the ping command on a Windows XP computer
(mine!), which by default sends four 32-byte Echo messages and
allows four seconds before considering an Echo message lost.
I use a satellite Internet connection that has fairly high latency and
also occasionally drops packets. This isnt great for me, but it
is useful for illustrating how ping works.
