You can use a program called ZoneEdit, which allows you to host domain names via you Dynamic IP. So that means you do not need a static IP address.
Also, I would not recommend becoming an ICANN registrar. Domain registrar's make very little from what they sell. Companies like GoDaddy, rely on
selling services like Hosting, Email, VeriSign certificates to make money.
