MySQL user account 'From Host' setting I've just installed Wamp server 2 and I get the following 4 default MySQL users:  

    USER         FROM HOST
    &lt;anonymous&gt;  localhost
    root         localhost
    root         127.0.0.1
    root         ::1


What does the ::1 mean?
I think that is the new way to express home based on the IPv6 protocol. It's new to me as well.

By this, my guess is your WAMP installed MySQL 5.5.

Just remember two things


There is no place like 127.0.0.1
There is no place like ::1
