## NAME
       get_root_domain - Retrieve suffix info from a domain using [Domain::PublicSuffix](https://www.chedong.com/phpMan.php/perldoc/Domain%3A%3APublicSuffix/markdown)

## DESCRIPTION
       The get_root_domain utility uses [Domain::PublicSuffix](https://www.chedong.com/phpMan.php/perldoc/Domain%3A%3APublicSuffix/markdown) to get the root or suffix for a fully
       qualified domain name. Given a FQDN, this utility will output the "root domain", and the
       suffix and TLD used to calculate that root domain.
