Answer 1

You are attempting to ping:

ping http://78.47.156.188/

Using ping is strictly an ICMP networking task; the http:// is not useful here. It makes ping believe you are attempting to ping the full hostname of http://78.47.156.188/ when the http:// and trailing / are just URL protocol parts. You should be pinging like this:

ping 78.47.156.188

And for the hostname it should be like this:

ping example.com
