Description
Someone might use a VPN through Amazon or other cloud providers and we falsely don't track them. How can we detect these VPN providers without a third party and without slowing down?
I don't think checking for headers might work reliably like in https://www.ipqualityscore.com/articles/view/1/how-to-detect-proxies-with-php
There seem to be DBs but they might be commercial like https://www.ip2location.com/database/px10-ip-proxytype-country-region-city-isp-domain-usagetype-asn-lastseen-threat-residential
I suppose it will not be possible to reliably detect them (and fixed IP addresses will change over time etc). Maybe we could check if some VPN providers disclose IP ranges (since sometimes you need to whitelist them eg in AWS, or WP etc but then you might just get a dedicated IP)

Research direction
No files, tests, or entry points are named. Start by reviewing the plugin's existing tracking and IP-handling behavior, then assess provider IP ranges, headers, and third-party databases against the requirements of reliable detection without added latency. Done should mean a documented, maintainable approach with clear reliability and performance limits.
