Dos prompt windows 7 ping

One of these commands is ping. Ping is a network diagnostics tool for the Windows command prompt. In network diagnostics, the command line program enables you to verify if another computer is available in a connected local or public network.

If the target computer is not located in the same local network as the source computer, it is necessary to specify the domain. The name ping is an analogy to sonar technology — a technique to locate objects by emitting pulses of sound that was employed during World War II to locate submarines.

As a result, the unavailability of the target computer cannot be inferred from an unanswered ICMP request. Normally in this case a router responds that either the network or the appropriate host is not available. If there is no response from the router, it can be assumed that the computer is in fact available but is not automatically responding to the echo request due to its configuration. The response time specifies how long a data packet requires to be sent to the target computer and back.

The initial value amounts to a maximum of Usually, implementations have an initial TTL of either 31, 63 or The TTL is reduced by 1 by every network node that the data packet passes.

This is referred to as hops. Should the TTL drop to 0, the data packet is rejected. With a TTL of 58, for example, you can assume that the response packet was dispatched with an initial value of 63 and passed five network nodes on the way back. The TTL is only moderately informative. In network diagnostics, the command line program provides ping information about the quality of the network connection between two computers. Follow these instructions for using a ping test to determine if the routing between your system and that of the target computer is functioning and what sort of delay you can expect when transferring data.

In this article. Specifies ping continue sending echo Request messages to the destination until interrupted. Specifies reverse name resolution be performed on the destination IP address.

If this is successful, ping displays the corresponding host name. Specifies the length, in bytes, of the Data field in the echo Request messages. The default is The maximum size is 65, The echo Request message can't be fragmented by routers in the path to the destination.

The default is the default TTL value for the host. The maximum TTL is The default is 0. TOS is specified as a decimal value from 0 through The command prompt allows Windows users to issue DOS commands to the system.

DOS commands are useful to Windows users for a variety of reasons. Many tasks that can be performed in the Windows graphical environment can be performed much more quickly and efficiently by utilizing DOS commands.
