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

be careful, there are other url schemes in use; for example, google.co.uk — PA.

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.
