In 2017, ICANN started a project to monitor the health of the registered identifiers ecosystem, through a set of Identifier Technology Health Indicators (ITHI), or ITHI Metrics. There are eight detailed metrics for which data can be seen on this site. The metrics are computed using data captured from various sources including data collected by ICANN projects and traces obtained from participating root DNS servers, authoritative DNS servers, and recursive DNS resolvers. Our first data collection partners are:
