Public Suffix List/LIST FORMATについて、ここに記述してください。

http://publicsuffix.org/list/

Specification
 * The list is a set of rules, with one rule per line.
 * Each line is only read up to the first whitespace; entire lines can also be commented using //.
 * Each line which is not entirely whitespace or begins with a comment contains a rule.
 * Each rule lists a public suffix, with the subdomain portions separated by dots (.) as usual.
 A leading dot is optional.
 * The wildcard character * (asterisk) matches any valid sequence of characters in a hostname part.    
 (Note: the list uses Unicode, not Punycode forms, and is encoded using UTF-8.)
 * Wildcards may only be used to wildcard an entire level.
 That is, they must be surrounded by dots (or implicit dots, at the beginning of a line).
 * If a hostname matches more than one rule in the file,
 the longest matching rule (the one with the most levels) will be used.
 * An exclamation mark (!) at the start of a rule marks an exception to a previous wildcard rule.
 An exception rule takes priority over any other matching rule.
