All Implemented Interfaces:

public class DomainSuffixes

                    
```
A Top-Level Domain is the suffix tied to a website, such as com, net, or org.
A top-level domain (TLD) is the suffix or extension tied to a website. Around half of all websites use the top-level domain com, commonly called “dot” com. There is no algorithmic way of knowing whether a suffix is a public domain suffix, or not.
