This video tutorial will explain everything about database hostnames: what these are, which one you’ll need to use and how.
A database hostname shows the physical location of your database. A database hostname allows you to install software like WordPress and Joomla and add extra features to your website such as content management systems, blogs and forums.
The video will also show you where in your 123-reg control panel you can manage and find out more information about your database hostname.
