Your site actually uses multiple IP addresses for different services.
WPhost's Cloud Platform uses shared load balancers (IP addresses) while still providing each WordPress site its own dedicated resources.
On WPhost, using our containerized server technology, our caching layer is the first part of our stack that a request to your site hits (one IP address), before being routed to a Google Cloud ingress point (another IP address), and from there it goes to one of your site’s containers (a third IP address). Outgoing requests from your site can also originate from any number of dynamic IPs. Additionally, if you use Cloudflare to route traffic to your site, that’s an extra IP address again!
