"int" domain

["MURAKAMI" <MURAKAMI@jeida.or.jp>]

     I want to know about the  "int" domain, like eu.int as the European 
     Union. Who authenticate and who can get the domain name?
     Are there some official document about that?
     I think that kind of domain name was not exist some months ago.   
     
     Plese let me know about that.
