Significant challenges remain for gTLD registry operators, particularly when Reference Label Generation Rulesets (LGRs) are not available for specific scripts or languages. In such cases, the manual development and submission of gTLD IDN tables become critical for the successful inclusion of these languages in the DNS. This process, while necessary, introduces complexities that ICANN must address to ensure a secure, stable, and efficient system.

1. Innovating gTLD IDN Table Submissions in the Absence of Reference LGRs

When Reference LGRs are unavailable, gTLD registry operators must take on the responsibility of developing their own IDN tables. This process, while tailored to specific linguistic communities, presents challenges in ensuring that gTLD IDN tables adhere to the necessary security and stability standards. Without a pre-existing Reference LGR to validate these tables, the potential for human error, security vulnerabilities, and operational instability increases.

Recommendation: ICANN may consider developing an enhanced, AI-driven validation tool tailored specifically for cases where Reference LGRs do not exist. This tool could incorporate machine learning algorithms that cross-reference historical IDN data, linguistic databases, and community-specific script rules. By preemptively detecting potential issues—such as homoglyph attacks, character confusability, and improper script usage—this tool would ensure that custom IDN tables are secure and stable before submission.

2. Strengthening Security Protocols for gTLD IDN Submissions

The absence of Reference LGRs requires more stringent oversight of custom IDN submissions, particularly from a security standpoint. Custom tables introduce a higher level of uncertainty, and as such, ICANN must be proactive in detecting and mitigating potential threats arising from new script deployments.

Recommendation: ICANN should integrate advanced security testing into the IDN submission process, specifically tailored to identify vulnerabilities associated with gTLD IDN tables. This could involve the inclusion of enhanced penetration testing and simulation of real-world attacks targeting custom scripts. Additionally, ICANN could provide automated security audits for gTLD registry operators submitting IDN tables, ensuring that these tables do not inadvertently introduce vulnerabilities into the DNS infrastructure.

3. Collaborative Development of Custom LGRs

ICANN’s Registry System Testing (RST) protocols have been effective in safeguarding the operational security of new and existing gTLD registries. However, when a Reference LGR is unavailable, the gTLD registry operator is left to develop custom LGRs without standardized guidance. This can lead to inconsistencies across registry operations and create unnecessary complexity in DNS management.

Recommendation: ICANN could establish a collaborative development framework for custom LGRs, leveraging global expertise in linguistics, cybersecurity, and DNS operations. This framework would facilitate the creation of community-specific LGRs in a standardized format that can be adopted by multiple registries. By sharing resources, knowledge, and best practices, registry operators can ensure that their custom LGRs align with ICANN’s security and stability guidelines while also addressing the unique needs of local communities.

4. Supporting Emerging Markets through IDN Development (Very important)

Many emerging markets, particularly in regions with diverse linguistic communities, are prime candidates for new IDN deployments. However, these markets often lack the technical expertise and resources needed to develop secure and stable IDN tables in the absence of Reference LGRs. This can hinder the growth of local internet infrastructure and limit the potential for global internet inclusivity.

Recommendation: It would be very wonderful if ICANN introduces a dedicated support program for registry operators in emerging markets. This program could provide technical assistance in the development of custom IDN tables, offer financial subsidies for regions with low internet penetration, and create mentorship opportunities with established registry operators. By focusing on capacity-building within these regions, ICANN can ensure that diverse linguistic communities are represented in the DNS without compromising security or stability.

Without pre-established Reference LGRs, the responsibility falls on gTLD registry operators to manually create and validate custom IDN tables, a process that introduces significant complexities, including heightened risks of security vulnerabilities and operational instability.

To address these challenges, the submission proposes several key recommendations. First, ICANN should consider the development of an AI-driven validation tool that leverages machine learning and linguistic databases to detect potential issues such as homoglyph attacks, character confusability, and improper script usage in custom gTLD IDN tables. This would ensure that security and stability are maintained even when manual submissions are required.

Second, the submission emphasizes the need for advanced security protocols specifically tailored to gTLD IDN table submissions. These would include enhanced penetration testing and automated security audits to proactively identify vulnerabilities before they can impact DNS infrastructure. Such measures would provide gTLD registry operators with a robust safety net, ensuring that custom tables meet ICANN's rigorous standards.

Third, a collaborative development framework is proposed to facilitate the creation of custom LGRs in cases where Reference LGRs do not exist. By leveraging global expertise in linguistics, cybersecurity, and DNS operations, ICANN can promote standardized, community-specific LGRs that ensure consistency and security across gTLD registry operations.

Finally, the submission advocates for targeted support to emerging markets, where diverse linguistic communities may lack the resources to develop secure and stable IDN tables. ICANN is encouraged to introduce a dedicated support program offering technical assistance, financial subsidies, and mentorship opportunities to gTLD registry operators in these regions. This would ensure that global inclusivity is achieved without compromising DNS security and operational stability.
