Measuring and Reporting DNSSEC Adoption in Your Zone

As the 2026 new gTLD program brings a new cohort of top-level domains into the DNS ecosystem, registry operators face heightened expectations regarding the implementation and transparency of security best practices. Among these, DNS Security Extensions, or DNSSEC, remain a critical cornerstone for ensuring data integrity and authentication at the DNS layer. For all new gTLDs, DNSSEC is a mandatory feature under ICANN’s Registry Agreement, but beyond initial deployment, the ongoing measurement and reporting of DNSSEC adoption within the zone is essential to demonstrate operational excellence, maintain trust among stakeholders, and support broader internet security objectives. Effectively tracking and communicating DNSSEC metrics requires a deliberate strategy that combines robust technical instrumentation with clear reporting frameworks.

DNSSEC works by cryptographically signing DNS data to prevent tampering or forgery, ensuring that when users look up domain names, they receive authentic responses from the correct authoritative servers. Registry operators enable DNSSEC at the TLD level by publishing DS records in the root zone and supporting signed delegation of second-level domains. However, the actual adoption of DNSSEC depends on registrants opting to sign their individual domain names, and registrars facilitating this process through user-friendly interfaces and automated key management. For registry operators, measuring DNSSEC adoption within the zone means tracking how many second-level domains are signed, monitoring the validity of those signatures, and identifying trends or patterns that inform policy and outreach.

The first and most direct metric of DNSSEC adoption is the percentage of active second-level domains in the TLD that include DS records in the zone file. This figure provides a baseline indicator of adoption and can be calculated by regularly parsing the TLD zone file and extracting entries with DNSKEY or DS records. Tools such as Zonemaster, DNSViz, or custom scripts built on libraries like dnspython can automate this process and provide time-series data showing how adoption evolves over weeks, months, or quarters. This metric is particularly useful for evaluating the impact of registrar education efforts, promotional campaigns, or changes in registry policy that encourage signing.

Beyond the raw number of signed domains, registry operators should also assess the quality and stability of DNSSEC implementations. This includes verifying that DS records match their corresponding DNSKEY records, that signatures are valid and unexpired, and that algorithm usage aligns with current best practices as outlined by the IETF and security communities. Misconfigured DNSSEC can be more damaging than no DNSSEC at all, potentially leading to domain resolution failures, user lockouts, and support escalations. Tools such as RIPE Atlas probes, Verisign’s DNSSEC Analyzer, and DNSCheck can help registries identify signing errors or propagation issues that affect domain resolution across global resolvers.

Reporting DNSSEC adoption is not only a matter of internal monitoring, but also of communicating security posture to external stakeholders. ICANN compliance requirements include periodic reporting obligations, and registry operators are encouraged to publish DNSSEC adoption statistics in their annual reports, public dashboards, or technical blogs. Providing transparency around these metrics reinforces the registry’s commitment to DNS security and allows registrars, regulators, and researchers to track progress in securing the namespace. Reports should include not only adoption rates but also key milestones, incident summaries related to DNSSEC (if any), and descriptions of outreach or support programs aimed at increasing adoption.

In addition to traditional reporting, registries may choose to integrate DNSSEC metrics into registrar engagement strategies. Registrars play a critical role in enabling or impeding DNSSEC deployment, depending on whether they offer DNSSEC signing tools, automate key rollovers, or simplify user interfaces for enabling DNSSEC. By sharing adoption metrics with registrars—especially in anonymized or aggregated formats—registry operators can incentivize higher adoption rates, identify best practices, and collaborate on improving registrar-side DNSSEC offerings. Some registries may also introduce DNSSEC adoption programs that reward registrars with marketing support, reduced fees, or public recognition when they meet specific signing thresholds.

Another dimension of DNSSEC adoption measurement is the analysis of resolver validation rates. While this aspect lies outside the direct control of the registry, understanding how often signed records are validated by recursive resolvers can help assess the real-world impact of DNSSEC. Data from initiatives such as APNIC Labs or the DNSSEC Deployment Initiative can provide insights into regional and global trends in DNSSEC validation, offering context for the registry’s internal efforts. If a registry operates in a market with high DNSSEC resolver support, the case for promoting adoption among registrants becomes even stronger, as end users are more likely to benefit from the protection it offers.

Security event monitoring should also incorporate DNSSEC data. For instance, DNSSEC validation failures can be early indicators of DNS spoofing attempts, key mismanagement, or software compatibility issues. Logging and analyzing these events enables proactive remediation and can support forensic investigations in the case of security incidents. Advanced registries may implement Security Information and Event Management (SIEM) platforms that include DNSSEC-related alerts and logs, contributing to a holistic view of registry security posture.

Looking forward, ICANN and the broader DNS community are likely to increase scrutiny of DNSSEC deployment as part of their efforts to secure the internet’s core infrastructure. This may include more detailed compliance audits, expanded best practice frameworks, and performance benchmarks tied to DNSSEC quality. Registry operators that invest in comprehensive DNSSEC measurement and reporting practices will be better positioned to meet these expectations and to lead by example in promoting a safer DNS environment.

In conclusion, DNSSEC adoption is not a one-time checkbox in the lifecycle of a new gTLD—it is an ongoing responsibility that requires continuous measurement, quality assurance, and public reporting. As the internet’s security challenges evolve, so too must the operational discipline of registry operators. By building systems to track adoption, analyzing deployment quality, engaging registrars, and sharing results transparently, registries can ensure that their zones are not only technically compliant but meaningfully secure. In the context of the 2026 gTLD program, those who treat DNSSEC as a strategic asset rather than a regulatory burden will be better prepared to earn the trust of users, partners, and the global internet community.
