When diagnosing networking problems, I ping to:
- My local IP
- My gateway IP
- An external IP
- An external domain name
Usually, when troubleshooting, the internet is unaccessible, then I need to remember an external IP address.
I need any (easy to remember) IP address. By example, google ip is 72.14.204.147. Cool, but it's hard to remember...
What external IP you use? Do you have an mnemonic external IP address, then will be easy to remember?
DNS Servers are "ping'able"? – Click Ok – 2010-01-16T15:39:52.703
4As a general answer yes. Whether a server is pingable or not has nothing to do with what the server does. As a specific case(8.8.8.8 & 8.8.4.4) yes those do pong back. – Kevin M – 2010-01-16T15:47:59.473
3btw: Google's infrastructure is more than "one server" per IP address. And: you will never know, if it is the same "server" which responds to different services. Depends how they structure their network/routers/load balancing systems. – splattne – 2010-01-16T19:19:37.440
