ping [-t] [-a] [-n Count] [-l Size] [-f] [-i TTL] [-v TOS] [-r Count] [-s Count] [{-j HostList | -k HostList}] [-w Timeout] [TargetName]
Parameters
-t : Sends echo request messages to the destination until interrupted by CTRL-C.
-a : Preforms reverse name resolution for the destination IP address.
-n Count : Specifies the number of Echo Request messages sent. The default is 4.
-l Size : Specifies the length, in bytes, of the Data field in the Echo Request messages sent. The default is 32. The maximum size is 65,527.
-f : Specifies that Echo Request messages are sent with the Don’t Fragment flag in the IP header set to 1.
-i TTL : Specifies the value of the TTL field in the IP header for Echo Request messages sent. The default TTL value for the host is typically 128. The maximum TTL is 255.
-v TOS : Specifies the value of the Type of Service (TOS) field in the IP header for Echo Request messages sent. The default is 0. TOS is specified as a decimal value from 0 to 255.
-r Count : Specifies that the Record Route option in the IP header is used to record the path taken by the Echo Request message and corresponding Echo Reply message.
