FQDN is null when an SLD is also an FQDN and null when the subdomain is a wildcard

[CyberCabano]

Some SLDs are also FQDNs, such as WordPress.com or CentralNIC’s SLDs like br.com, but the library returns a null FQDN in these cases. Wildcards should also be considered FQDNs, as is the case with web servers and X509 certificates.

Hi, could you perhaps explain what you want with an example? I don't quite understand yet.
