ip - What does MySQL "::1" hostname refer to?

Question

On a freshly installed (windows version of) MySQL 5.5.9

SELECT user, host FROM mysql.user

gives:

user            host    

root        localhost   
root        127.0.0.1    
root        ::1  
localhost    

But what IP/hostname does ::1 stand here for?

question from:https://stackoverflow.com/questions/5081475/what-does-mysql-1-hostname-refer-to

Answer 1

::1 is the IPv6 address for localhost.
