I am trying to set up a mysql master/slave configuration in two EC2 instances.

However, every time I reboot an instance, the IP address (and hostname) changes. I could assign an Elastic IP address, but would prefer to use the internal IP address.

I can't be the first person to do this, but I can't seem to find a solution. There are a lot of "getting started" guides, but none of them mention how to handle changing IP addresses. So what are the best practices to manage master/slave replication in EC2?
