Introduction
When experiencing issues between your cPanel server and another server, you may need to check what IP address your server is attempting to use. The easiest method is to use 'ping' from inside your server.
Procedure
In our example, we will use google.com as the domain whose IP we are looking for.
Log into your server using SSH or an appropriate method.
Use the 'ping google.com' command.
Linux:
Log into Linux-based server with SSH.
Type "ping google.com" on command-line, hit Enter.
# ping google.com

The output will tell you what IP address the server is using for the domain.
This method is 'quick', but may not reflect what services are using. This guide is to get an idea of what IP is from inside your server.
