Identifier Technical Health Indicator Project

The Identifier Technical Health Indicators (ITHI) project is an initiative by ICANN to improve the security, stability and resiliency of the Internet’s unique identifier system, by developing metrics to measure the health of this unique identifier system.

At the request of ICANN, the Regional Internet Registries (RIRs) are providing input through measurement of the accuracy of its registry data. Accuracy is critical to the reliability of the RIR whois databases, as this data is publicly available.

The NRO’s Registration Services Coordination (RSCG) and Engineering Coordination Groups (ECG) have developed a proposal for how the RIRs can identify and measure risk associated with registry data accuracy.

For the purposes of measuring the state of the data, accuracy has been defined as ‘comprehensive, correct, and current’.

Community Consultation

The RIRs launched a call for comment on 11 September 2017 to gather feedback for the proposal, specifically on:

  • The definition of the risks and measurements to report on registry data accuracy
  • The proposed approach
  • The proposed measurement matrix
  • Other information as how often to measure, where to post results, and what formats to use to share the results

As a result of the consultation and further internal RIR collaboration the RSCG has updated the proposal document to continue its work on the ITHI project.
