How to use PING

Apr 21, 2009

The ping (Packet Internet Groper) is used to send ICMP (Internet Control Message
Protocol) packets from one host to another. Ping transmits packets using the ICMP
ECHO_REQUEST command and expects an ICMP ECHO_REPLY. Ping is the primary TCP/IP command used to troubleshoot connectivity, reachability, and name resolution.

Syntax
ping [-t] [-a] [-n Count] [-l Size] [-f] [-i TTL] [-v TOS] [-r Count] [-s Count] [{-j HostList | -k HostList}] [-w Timeout] [TargetName]

Switches:
-t Ping the specifed host until interrupted.
-a Resolve addresses to hostnames.
-n count Number of echo requests to send.
-l size Send buffer size.
-f Set Don’t Fragment flag in packet.
-i TTL Time To Live.
-v TOS Type Of Service.
-r count Record route for count hops.
-s count Timestamp for count hops.
-j host-list Loose source route along host-list.
-k host-list Strict source route along host-list.
-w timeout Timeout in milliseconds to wait for each reply.

Examples
The following example shows ping command output:

C:\>pimg example.microsoft.com

Pinging example.microsoft.com [192.168.239.132] with 32 bytes of data:
Reply from 192.168.239.132: bytes=32 time=101ms TTL=124
Reply from 192.168.239.132: bytes=32 time=100ms TTL=124
Reply from 192.168.239.132: bytes=32 time=120ms TTL=124
Reply from 192.168.239.132: bytes=32 time=120ms TTL=124


To pingthe destination 10.0.99.221 and resolve 10.0.99.221 to its host name, 
type: ping -a 10.0.99.221

To ping the destination 10.0.99.221 with 10 Echo Request messages, each of which has a Data field of 1000 bytes, 
type: ping-n 10 -l 1000 10.0.99.221

To ping the destination 10.0.99.221 and record the route for 4 hops,
type: ping-r 4 10.0.99.221

To ping the destination 10.0.99.221 and specify the loose source route of 10.12.0.1-10.29.3.1-10.1.44.1,
type: ping -j 10.12.0.1 10.29.3.1 10.1.44.1 10.0.99.221
