Hashed Email to IP

8 fieldsRefreshed monthlyLast updated 14 Aug 2026

The hashed email to IP linkage, used for household-level targeting and for resolving anonymous site traffic. Each row pairs the hashes of an email with an observed IP address, an approximate latitude and longitude, an accuracy radius, and the date the pairing was last seen. Treat an IP as a household or a network, never as a person on its own.
