====== Public Suffix ======
A public suffix is a set of DNS names or wildcards concatenated with dots. It represents the part of a domain name which is not under the control of the individual registrant.

Public suffixes are often privately owned.

''blogspot.com'' and ''github.io'' are public suffixes. They can have subdomains that are not controlled by those private companies.


e.g. ''*.compute.amazonaws.com'' is a public suffix.
