We're not sure we understand the nature of the question.
Cloud integration simply means routing traffic through the reverse proxy setup - the host remains in place, with no change to where the actual content is being hosted (the server IP that's dedicated to the site).

Having a dedicated IP address typically means access to more options with the host - such as whitelisting proxied IPs like you'd be using with Ezoic. We have many, many sites using Hostinger without issue via cloud methods of integration. It sounds like there's a misunderstanding of what a cloud integration with Ezoic means exactly, so we'd encourage you to read the guide above and have a look around the support.ezoic.com guides on the topic to help with your understanding.
