Test a network connection - if successful, ping returns the ip address.
Syntax PING [options] destination_host Options -w timeout Timeout in milliseconds to wait for each reply, default=4000. -i TTL Time To Live. -v TOS Type Of Service. -a Resolve addresses to hostnames. -n count Number of echo requests to send. -t Ping the destination host until interrupted. To see statistics and continue type Control-Break; To stop type Control-C. -l size Send buffer size (default=32). -f Set don’t Fragment flag in packet (IPv4-only). -r count Record route for count hops (IPv4-only). -s count Timestamp for count hops (IPv4-only). -j host_list Loose source route along host_list (IPv4-only). -k host_list Strict source route along host_list (IPv4-only). destination_host The name of the remote host -R Use routing header to test reverse route also (IPv6-only). -S srcaddr Source address to use. -4 Force using IPv4. -6 Force using IPv6.
A response of "Request timed out" means there was no response within the default time period.
A successful PING does NOT always return an %errorlevel% of 0
Therefore to reliably detect a successful ping, pipe the output into FIND and look for the text "TTL"
Note that "Reply" in the output of PING does not always indicate a positive response.
Example message: Reply from 192.168.1.254: Destination Net Unreachable.
Ping defaults to an ICMP timeout of 4000ms or 4 seconds. When specifying very small numbers (<500) for timeout with -w , the Ping reply can be received even if timeout milliseconds have elapsed.
When pinging a host that doesn't exist or is offline there will be a delay of some seconds before it is returned as 'host not found'.
The PING -w and the WMI Get-CIMInstance Win32_PingStatus timeout=NNN options both offer to control the Timeout, but this is the ICMP timeout not the DNS client timeout.
When sucessfully contacting a host, the ICMP timeout is used (default typically 4 seconds) but when attempting to PING a non-existent or offline computer it will be a DNS timeout causing the delay, typically around 9 - 10 seconds.
The time to respond as 'host not found' is for the first response, once you have pinged a host once, DNS will cache the (non) response and respond much faster to a second PING.
The performance of PING, Get-CIMinstance, PSPING and Test-Connection (PowerShell) are all comparable, the only difference being that PING and Get-CIMinstance allow modifying the ICMP timeout.
1) Ping the loopback address to verify that TCP/IP is installed and configured correctly on the local computer.
2) Ping the IP address of the local computer to verify that it was added to the network correctly.
3) Ping the IP address of the default gateway to verify that the default gateway is functioning and that you can communicate with a local host on the local network.
4) Ping the IP address of a remote host to verify that you can communicate through a router.
Create a delay of 1 or more seconds by pinging the loopback address (127.0.0.1) multiple times.
The delay between each ping is 1 second, so for a delay of 5 seconds ping 6 times:
PING -n 6 127.0.0.1>nul
In tests this consumes less processor time than Sleep or Timeout - see Clay Calvert's original newsgroup posting.
Ping response times below 10 milliseconds often have low accuracy. A time of 10 milliseconds is roughly equal to a distance of 1860 Miles, travelling a straight line route at the speed of light, (or a round trip of 2 × 930 miles). From this you can see that ping response times will give a very very rough estimate of the distance to a remote host.
Network adminstrators do not appreciate frequent or continual pings to their servers, try not to overdo it!
The IPv6 options are only available on versions of Windows that support IPv6.
Ping a server just once:
PING -n 1 Server64
Check if a host is reachable:
PING Server64 |find "TTL=" && ECHO MyHost found
Check if a host is not reachable:
PING Server64 |find "TTL=" || ECHO MyHost not found
Test which iSCSI IP on a specific NIC is functioning or if a specific teamed NIC is operating as it should:
Ping -S (Source IP: XXX.XXX.XXX.XXX) (Destination IP: XXX.XXX.XXX.XXX)
Ping -S 10.5.7.64 10.5.7.1
Ping a website 5 times:
PING -n 5 -w 7500 www.microsoft.com
Monitor a website (example.com) every 15 seconds:
@Echo off Echo Logging ping responses, press CTRL-C to stop :start Ping -n 1 example.com | find "TTL=" >>c:\pingtest.txt Echo . Ping -n 16 127.0.0.1>nul goto start
The script above can be used to test an Internet connection, just replace example.com with your ISP's Default Gateway IP address. This represents the first physical device on the ISP's side of your connection. You can find the Default Gateway on your router status screen.
PING is named after the sound that a sonar makes.
