Ping | NT 4.0 Home | NT System Utilities |


Ping - Is a UNIX, windows95/windows NT, DOS command, which forwards a packet to a URL over the internet or within an Intranetwork. It is used with the TCP/IP protocol.

The packet is sent to either a standard named URL such as www.techadvice.com or to a TCP/IP address such as 209.132.55.215

The correct usage for ping is

Ping www.techadvice.com <enter>)

or

Ping 64.85.4.38 <enter>

 

The ping command will send 4 packets to the indicated address and respond with the time it takes for the packets to return.

Important Note: You can test the TCP/IP connection stack on your own computer by issuing the ping command with the "Loopback address" of your very own computer. The Loopback address for all computers is 127.0.0.1

so to test your own computers TCP/IP operation you would type

ping 127.0.0.1

Note: a failed "ping" at address 127.0.0.1 probably indicates that your computer is not setup with the TCP/IP protocol. To correct that you need to go to Control Panel, Networks and install the TCP/IP service.

Example:

D:\>ping 127.0.0.1

Pinging 127.0.0.1 with 32 bytes of data:

Reply from 127.0.0.1: bytes=32 time<10ms TTL=128
Reply from 127.0.0.1: bytes=32 time<10ms TTL=128
Reply from 127.0.0.1: bytes=32 time<10ms TTL=128
Reply from 127.0.0.1: bytes=32 time<10ms TTL=128

 

If ping responds with "request timed out" then there was NO response at the calling address ( the site you were calling was probably down ).

Remember, accuracy counts in typing in addresses.

A similar function is performed with TRACERT.
