Get root domain from request

Question

Consider the below URL as an example. http://www.test1.example.com

Is there any method by which I can get \"example.com\" as an output. I know there is

Answer 1

We have more reliable way of doing the same. There is google library "guava". Add following dependency in your pom.

     com.google.guava
     guava
     19.0

Then try

InternetDomainName.from("subdomain.example.co.in").topPrivateDomain().toString()

This will give you "example.co.in"
