How to find out the ping to the site?

Question

JavaScript

How can you find out in a simple way ping to the site, or even better, immediately get the external ip.

It is necessary to check the proxy before use, I tried the standard ping command, but did not find information on how to extract values ​​from it.
Also, it does not pass through the proxifier, it simply does not transfer it to the proxy server.
