Hello Larrym14169, Thanks for the question - as brief as it is! In general, the you can set yourmysql host name to "localhost". The MySQL server is "local" to your website unless you're linking to an outside server running your database. If you're referring to your hosting account, then by default, it will always be "localhost". I hope this answers your question! Please let us know if you require any further assistance! Regards, Arnel C.
