Contention Resolution for New gTLD Strings

The introduction of new generic top-level domains (gTLDs) has fundamentally reshaped the domain name system (DNS), expanding the namespace to accommodate a diverse range of industries, communities, and creative expressions. While this expansion has unlocked vast opportunities, it has also introduced significant complexities, particularly in the form of contention over gTLD strings. Contention occurs when multiple parties apply for the same or confusingly similar gTLD string during the application process. Resolving these disputes is a critical aspect of namespace management, requiring a structured approach that balances fairness, transparency, and operational efficiency while adhering to the policies established by the Internet Corporation for Assigned Names and Numbers (ICANN).

The contention resolution process begins during ICANN’s new gTLD application phases, where entities submit proposals for specific gTLD strings. These proposals are reviewed against a rigorous set of technical, financial, and operational criteria to ensure that applicants have the capability to operate a secure and reliable registry. However, when two or more applicants submit identical or similar strings, ICANN must determine how to allocate the rights to the contested TLD. This process is vital to maintaining the integrity and stability of the DNS, as delegating a gTLD to multiple operators or allowing similar strings to coexist without safeguards could create confusion and operational conflicts.

One of the primary methods for resolving string contention is community priority evaluation (CPE). CPE is designed to give preference to applications that serve a clearly defined community with a legitimate claim to the string in question. For instance, an organization representing a specific cultural or professional group might seek a gTLD that reflects its identity, such as .eco for environmental organizations or .bank for the financial sector. To qualify under CPE, applicants must demonstrate that their proposal meets specific criteria, including community endorsement, alignment with the community’s goals, and restrictions on use to ensure the TLD benefits the intended audience. If a community application passes CPE, it gains priority over standard applications, effectively resolving the contention.

For cases where CPE does not apply or fails to produce a clear outcome, contention is often resolved through auctions. Auctions are considered a last resort, used when competing applicants cannot reach a mutual agreement or when no community claim exists. In these scenarios, applicants bid against one another for the rights to operate the gTLD, with the highest bidder securing the string. Auctions can take various forms, including ascending-price models and sealed-bid formats, each with its own advantages and challenges.

Ascending-price auctions are the most commonly used format, allowing participants to bid progressively higher amounts until all but one withdraw. This approach ensures that the gTLD is awarded to the applicant that values it most highly, reflecting its perceived economic or strategic importance. However, the process can be contentious, particularly if smaller or community-focused applicants are outbid by larger commercial entities with greater financial resources. To mitigate such concerns, ICANN has implemented policies to allocate auction proceeds to projects that benefit the broader internet community, such as initiatives to enhance DNS security or support underserved regions.

Sealed-bid auctions, by contrast, require applicants to submit their highest bid upfront, with the gTLD awarded to the highest bidder. This method minimizes the risk of prolonged bidding wars and provides a level of confidentiality, which may be appealing in competitive industries. However, sealed-bid auctions can also introduce uncertainty, as applicants must gauge the value of the string without visibility into their competitors’ strategies.

In some instances, applicants may choose to resolve contention through private negotiations, bypassing the formal auction process. These negotiations can lead to joint ventures, partnerships, or other agreements that allow multiple stakeholders to benefit from the gTLD. For example, competing applicants might agree to share registry operations or to create a governance structure that reflects the interests of all parties involved. While this approach can foster collaboration and innovation, it also requires careful oversight to ensure compliance with ICANN’s policies and to prevent anti-competitive behavior.

Confusingly similar strings present additional challenges in contention resolution, as they may lead to user confusion or undermine the stability of the DNS. For example, strings like .hotel and .hotels or .app and .apps could create ambiguity for users and registrants, making it difficult to distinguish between TLDs. To address this issue, ICANN employs a string similarity review during the application evaluation process, identifying cases where competing strings are visually or phonetically similar. In such cases, ICANN may recommend changes to the proposed strings, request additional safeguards, or consolidate applications into a contention set for further resolution.

Beyond the immediate allocation of gTLDs, contention resolution has broader implications for namespace governance and equity. The introduction of new gTLDs has opened opportunities for innovation, branding, and community representation, but it has also raised concerns about access and fairness. Smaller organizations, non-profits, and community groups may struggle to compete with large corporations in auctions or may lack the resources to navigate the complex application process. To address these disparities, ICANN has implemented support programs, such as fee reductions and advisory services, to assist applicants from underserved regions or economically disadvantaged backgrounds.

The resolution of gTLD contention also highlights the importance of transparency and stakeholder engagement in namespace management. ICANN’s processes are designed to be open and participatory, allowing applicants, community members, and the public to provide input and raise concerns throughout the application and resolution phases. By fostering dialogue and accountability, ICANN seeks to ensure that the expansion of the namespace reflects the diverse needs and interests of the global internet community.

In conclusion, contention resolution for new gTLD strings is a complex but essential aspect of namespace management, balancing competing priorities to allocate valuable resources fairly and effectively. Through mechanisms such as community priority evaluation, auctions, and private negotiations, ICANN has established a structured framework to address disputes while maintaining the stability and trustworthiness of the DNS. As the namespace continues to evolve, the lessons learned from gTLD contention resolution will inform future policies and practices, ensuring that the DNS remains a dynamic and inclusive platform for innovation and communication.
