Do you mean IP, not ISP?
- yjftsjthsd-h 5y agoNo, I meant ISP, although IP could work as a special case - if this isn't recording the user's actual IP but just information derived from it (rough location, residential/commercial/datacenter, whatever), I would expect many addresses under that ISP to have the same recorded details. Granted, CGNAT with the same exact public IP would be even more like that, but if you don't record the actual IP then you probably can't deduplicate close "neighbors". (I should add that your sibling comment says they're using browser headers, which probably reduces this issue a lot)
- aviaviavi 5y agoInformation derived from IP can be much more granular than just ISP level
