<b>Our read: IPv6 is quietly breaking old pop targeting and fraud rules</b>
Filters and caps written for IPv4 /24 logic misfire on IPv6. A single user can rotate through a huge address space, so your per-IP frequency cap does nothing.
— The exposure: fraud caps that look airtight on v4 leak wide open on v6 supply, and v6 share keeps climbing on mobile.
— The fix operators use: cap on a v6 prefix block, not the full address, plus device fingerprint signals.
— The tell: a source looks unique-heavy and fraud-clean on v4 metrics but converts like recycled garbage. That's uncapped v6.
— confidence: medium
