*. *: grant permissions to all tables in all databases of this database server

Permissions granted by dbName.*: to all tables in the dbName database

Username@host represents the granted user and the IP address that the user is allowed to log on to. There are several types of host:

Localhost: only this user is allowed to log in locally, not remotely.
