Part of the Internet Registry System‘s mission is to help ensure that the Internet remains stable, resilient and secure. The NRO acts as a coordination point for several cross-RIR projects that help to promote and improve Internet security.


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 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. Find out more.


Domain Name System Security Extensions (DNSSEC) is an enhanced level of Internet security that allows authentication to be added to domain name records to ensure they are correct and not tampered with. This prevents hackers from falsifying DNS records in an attempt to re-direct people to fake, phishing or criminal sites. The RIRs’ Engineering teams collaborate on this cross-RIR project. Find out more.


Resource Certification, also referred to as Resource Public Key Infrastructure (RPKI), is a robust security framework for verifying the association between resource holders and their Internet resources. Resource holders are organizations such as Regional Internet Registries (RIRs), Local Internet Registries (LIRs), ISPs, or end-user organizations, while ‘Internet resources’ are IPv4 and IPv6 address blocks and Autonomous System Numbers (ASNs). The RIRs’ Engineering teams collaborate on this cross-RIR project. Find out more.
