This data may consist of a sparse statistical sampling of timestamped DNS responses from our cache or upstream authoritative servers, but no address, prefix, ASN, or other data related to the user or the query. It does not contain any PII or any data that we believe could be combined or correlated with PII to characterize a user or their behavior. When we provide such assistance, we do so only under a written agreement that the researcher use information we provide solely for the purpose of improving user security, and not for any other purposes.
