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