This is great info on how to substitute IP address or turn off user tracking. I do think the replacement is dubious ( especially forwarding to CF) and not GDPR compliment so I would use something else like user agent, timezone, languages to form a hash. It's doesn't need to be precise and in some ways it's good if it's a bit rough. I only want general trends on a website.

in fact it can't and shouldn't be precise, as this would still make the iser clearly identifiable. You have to discern between GDPR (which governs tracking purposes as well) and E-Privacy laws (which concern PII) here
