The TOP-Level domain of `example.google.com` and `google.com` is `com`. `google.com` is second level domain. The most righteous `.`-part is always the top-level, followed by second-level and so on. — Michael Konietzka, Jan 27 '11 at 08:26
be careful, there are other url schemes in use; for example, `google.co.uk` — PA., Jan 27 '11 at 09:44

With google guava (uses public suffixes)

final InternetDomainName topPrivateDomain = InternetDomainName.from(uriHost).topPrivateDomain();
topPrivateDomain.name();

Try the java library at http://sourceforge.net/projects/publicsuffix/
That might help since you need all known domain suffixes and I think that jar just do that.
