The mysql.host table is an obsolete table containing information about hosts and their related privileges. The table can be queried and although it is possible to directly update it, it is best to use GRANT for setting privileges.
Note that the MariaDB privileges occur at many levels, so this table alone does not give a complete overview into what privileges a user may or may not have. See privileges for a more complete view of the MariaDB privilege system.
