field 1: ASCII form (A-label)
field 2: unicode form (U-label) if an IDN otherwise empty
field 3: registry operator
field 4: date registry agreement signed
field 5: application number
field 6: date of delegation (empty if not yet delegated)
Fields 1,2 (if an IDN),3,4 from this csv are incorporated into the public suffix list publicsuffix.org/list/public_suffix_list.dat
For example, the csv entry for .コム is
xn--tckwe,コム,"VeriSign Sarl",2015-01-15,1-1254-37311,
It seems as though Chrome browser uses this public suffix list. One interesting (and IMHO good) consequence is that Chrome will recognise a .コム IDN (eg anything.コム ) as a domain name to be resolved even though it is not yet delegated. Chrome does not resort to a search. So Chrome is ready to go as soon as .コム is delegated.
