Counterintuitively, I DON'T want visitor IP address forwarded to my host

Something occurred in mid-December that led to visitor IP addresses being forwarded to my web host. I am not on one of the higher-tier plans so don’t know why this occurred. Because of how my host bills, this will mean a big jump in my monthly cost. Any ideas from the community on what may have happened and where I can check/uncheck a setting to revert to the old system, in which (typically) only Cloudflare IP addresses were sent along?

Visitor IP is always included in the headers as CF-Connecting-IP and X-Forwarded-For.

It’s up to your host to decide how to handle this. Maybe they started parsing these headers because it’s part of their billing process. You’d have to ask them.
