萍不回答

Ping is not the best tool to be used to test the availability of a remote network. 
Although ping can tell you that a network is reachable and send you response times, 
	the lack of that information does not imply that the network is down. 
As the saying goes, absence of evidence is not evidence of absence.

Open your browser and go to intel.com. 
	it come up
Try pinging Intel ping intel.com Intel doesnt return any ping results. 
	Intel probably disabled ping response for security reasons, like denying ping flooding.

Another issue with ping is that people often misinterpret the results. 
	If you are getting a long response time, people often blame the endpoint. 
	If you are in Windows, type pathping yahoo.com and you will see a combination of traceroute and ping,
		which gives much better information
