![]() ![]() The maximum value for count is 4, meaning that only the first four hops can be time stamped. Use this option to report the time, in Internet Timestamp format, that each echo request is received and echo reply is sent. The maximum value for count is 9, so use the tracert command instead if you're interested in viewing all the hops between two devices. Use this ping command option to specify the number of hops between your computer and the target computer or device that you'd like to be recorded and displayed. Beginning in Windows 7, this option no longer functions but still exists for compatibility reasons. This option allows you to set a Type of Service (TOS) value. This option sets the Time to Live (TTL) value, the maximum of which is 255. The -f option is most often used to troubleshoot Path Maximum Transmission Unit (PMTU) issues. Use this ping command option to prevent ICMP Echo Requests from being fragmented by routers between you and the target. The ping command will send a 32-byte echo request if you don't use the -l option. Use this option to set the size, in bytes, of the echo request packet from 32 to 65,527. The ping command will send 4 by default if -n isn't used. This option sets the number of ICMP Echo Requests to send, from 1 to 4294967295. This ping command option will resolve, if possible, the hostname of an IP address target. RFC5737 - IPv4 Address Blocks Reserved for Documentation.Įquivalent PowerShell: Test-Connection - Ping one or more computers, psp function.Įquivalent bash command (Linux): ping - Test a network connection.Using this option will ping the target until you force it to stop by using Ctrl+C. Q115388 - Resolving IP Address with Leading Zero. The very pulse of the machine” ~ William Wordsworth, (She Was a Phantom of Delight) Related commands PING is named after the sound that a sonar makes. You can find the Default Gateway on your router status screen. This represents the first physical device on the ISP's side of your connection. The script above can be used to test an Internet connection, just replace with your ISP's Default Gateway IP address. Ping -n 1 | find "TTL=" >c:\pingtest.txt PING -n 5 -w 7500 Monitor a website () every 15 offĮcho Logging ping responses, press CTRL-C to stop Test which iSCSI IP on a specific NIC is functioning or if a specific teamed NIC is operating as it should: PING Server64 |find "TTL=" || ECHO MyHost not found PING Server64 |find "TTL=" & ECHO MyHost found The IPv6 options are only available on versions of Windows that support IPv6. Network adminstrators do not appreciate frequent or continual pings to their servers, try not to overdo it! From this you can see that ping response times will give a very very rough estimate of the distance to a remote host. ![]() ![]() 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). Ping response times below 10 milliseconds often have low accuracy. In tests this consumes less processor time than Sleep or Timeout - see Clay Calvert's original newsgroup posting. Ping defaults to an ICMP timeout of 4000ms or 4 seconds. Note that "Reply" in the output of PING does not always indicate a positive response.Įxample message: Reply from 192.168.1.254: Destination Net Unreachable. Therefore to reliably detect a successful ping, pipe the output into FIND and look for the text "TTL" ![]() R Use routing header to test reverse route also (IPv6-only).Ī response of "Request timed out" means there was no response within the default time period.Ī successful PING does NOT always return an %errorlevel% of 0 k host_list Strict source route along host_list (IPv4-only).ĭestination_host The name of the remote host j host_list Loose source route along host_list (IPv4-only). s count Timestamp for count hops (IPv4-only). r count Record route for count hops (IPv4-only). f Set don’t Fragment flag in packet (IPv4-only).
