I have read a couple of posts on the forum here that suggest using a random string as a mysql host (rather than using mysql.yourdomain.com).
This makes sense to me, and I have started using this on new websites I set up.
Usually, when I am first setting up a website, I will use the thesite.dreamhosters.com subdomain to start with while I wait for DNS to propagate, or for my client to decide which domain they will use, etc.
I wonder then if it makes sense to just keep the sub-domain as the mysql host. For example: NY1G6qO3oq14RBe.thesite.dreamhosters.com ..not using the main domain at all as a mysql host, for even more obscurity
Can anyone think of reasons for or against this? Since the domains both point to the same place I would imagine there are no performance issues.
