The [[Public_Suffix_List|PSL]] is being used for more things than was originally intended, and various edge cases, which need to be "in" for one use but "out" for another, are causing people difficulty. This page attempts to gather those potential use cases and help us make a decision on which ones to support, and how.
The current definition according to publicsuffix.org is: 'A "public suffix" is one under which Internet users can directly register names.'
