+## -
+## - But in the free, open source fork, MariaDB, it's turned off by default, and
+## - you have to manually switch it on.
+## -
+## - It's turned off by default in MariaDB because there is a slight performance hit

+## -
+## - Whether to resolve host names when checking client connections. If this variable is OFF,
+## - mysqld resolves host names when checking client connections. If it is ON, mysqld uses
+## -  only IP numbers; in this case, all Host column values in the grant tables must be IP
+## - addresses. See Section 5.1.11.2, “DNS Lookups and the Host Cache”.
+## -
+## - Depending on the network configuration of your system and the Host values for your
+## - accounts, clients may need to connect using an explicit --host option,
+## - such as --host=127.0.0.1 or --host=::1.
+## -
+## - An attempt to connect to the host 127.0.0.1 normally resolves to the localhost account.
+## - However, this fails if the server is run with skip_name_resolve enabled. If you plan to
+## - do that, make sure an account exists that can accept a connection. For example, to be
+## - able to connect as root using --host=127.0.0.1 or --host=::1, create these accounts:
