URL not accessible from different machine. pls help

Am able to run tomcat and deployed my war file.
Able to run the app/rest web service via(
However, when I hit the above URL in some other machine, it returns nothing/blank.

I understand is a private ip but how I can run my application from ‘anywhere’? or do I need to subscribe docker account for that?
Please help or send me some url where I can learn this.
