What is you use an EC2 on AWS?
Your home IP address will not be revealed as a result of hosting a server using Amazon's cloud servers. Of course, the cloud server's IP address will be revealed to pretty much anyone.
The only problem with easily available real IP addresses of home users is that they might get DoS/DDoS'd. People can't just instantly hack you or usually know exactly where you live just by having your IP address. Your address is available to all of the servers and websites you use every day so don't worry about it too much.
