If you don't know what
ping is, it's a program that tests the network connection between your computer and another host. When you run it you can see how fast the connection is but people use it mainly to test if it's even possible to make the network connection.
Often when I've had to struggle to get connected to the network (fiddling with the Ethernet cable or getting on a wifi broadcast) I often use ping to see if the internet connection works. Which host do I ping? I use
For a long time I was using
www.google.com for no obvious reason. My colleague Zahid uses
yahoo.com I noticed yesterday when I was leaning over his shoulder after connecting to a wireless router. So, who do you ping? (and why?)

google.com for me - brandpower I guess...
It would take more than an instant of effort to think of any other url.
I use google.com as I also know the IP address so I can still ping if DNS isn't resolving.
I use the dns server of my ISP
Same as Erwin: First the DNS server of the ISP (which I have as an IP number), because it allows me to check if I have a connection even if I don't have a proper DNS setup.
Maybe the connection is broken from the ISP to the greater Net, then this test should still respond.
Then doing a dig to see if DNS works. Then pinging betabug.ch which is a poor choice since it's my own server and may be down too.
av.com (altavista) or qua.cz (my remote box, if I know it's up) -- because they're each just 6 characters to type.
ping.sunet.se, its even in the name :-)
google and my isp dns server .. just to be sure :))
av.com as I don't think that you can do it in any less characters
I'm want to know more about ping and telnet. what more can you do by knowing an IP address
