ping - send ICMP echo requests
ping host [size]
Command ping sends a series of four ICMP ECHO requests to a specified host. Argument host must be either an IP address or a fully-qualified DNS name.

For each ICMP ECHO Response received, ping prints the number of bytes received, the IP address of the host which sent the response, the elapsed time (in msec) since sending the request, and the ICMP sequence number of the response.

Finally, a summary of how many packets were sent and received and the loss rate is printed. The optional size argument specifies the ICMP echo request packet length (default 64 bytes).

Ping uses the NAT32 Network Interface(s). If only Winsock networking is available, ping will time out after about 5 sec.

ICMP Echo requests arriving at the Primary Interface will be ignored if the IP Address of the Primary Interface is being shared.
