Answer 1

I recently implemented a Public Suffix List API:

PublicSuffixList suffixList = new PublicSuffixListFactory().build();

assertEquals(
    "google.com", suffixList.getRegistrableDomain("example.google.com"));

assertEquals(
    "bing.com", suffixList.getRegistrableDomain("bing.bing.bing.com"));

assertEquals(
    "amazon.co.jp", suffixList.getRegistrableDomain("www.amazon.co.jp"));
