DNS operators, in particular Root Server Operators (RSOs), are periodically requested to collect query data and submit it to a central storage location where it is accessible for future research. The typical example is the yearly Day In The Life of the Internet (DITL) collections undertaken by the DNS Operations Analysis and Research Center (DNS-OARC). Some operators are uncomfortable sharing IP addresses of the query sources and some are even legally prevented from doing so. In those cases, the compromise has been for the RSO in question to anonymize the source IP addresses of the queries.
