In a recent attempt of moving an application from one server to another, I needed the MySQL server running on the old server on localhost to listen on another IP address. Digging into the MySQL documentation I realized there's only an all-or-nothing approach built into MySQL server. This means MySQL is only able to listen on one IP address or all IP addresses. Of course, I could have configured MySQL to listen on all IP addresses (networks) and then use a couple of firewall rules to lock access, this seems like a common approach.
