Alternate Root Implications for New gTLDs

As the 2026 round of the new gTLD program approaches, one topic generating increasing concern among policymakers, technical experts, and registry operators is the rising prominence of alternate root systems and their implications for the stability, interoperability, and legitimacy of new gTLDs. Alternate roots—non-ICANN-controlled domain name systems that operate outside the global authoritative root managed by the Internet Assigned Numbers Authority (IANA)—present a multifaceted challenge to the core principles of a single, unified, and globally resolvable Domain Name System. While these systems have existed for decades in various forms, their growing technical maturity, increasing deployment in specific jurisdictions, and alignment with geopolitical agendas introduce new variables that could impact the operational integrity and market viability of new gTLDs delegated through ICANN.

At the heart of the issue is the fundamental assumption underpinning ICANN’s multistakeholder model: that the DNS is a universal namespace, where each top-level domain is unique, globally recognized, and accessible regardless of geographic or network boundaries. Alternate roots challenge this assumption by creating parallel DNS hierarchies that may use overlapping or entirely conflicting top-level domain strings. For instance, a string delegated by ICANN in the 2026 round—such as .store or .health—could theoretically be duplicated in an alternate root system, serving a different registry, targeting a different user base, and operating under a completely separate governance model. In such cases, users depending on a resolver configured to access the alternate root might receive different or conflicting DNS responses than users relying on the ICANN root, undermining the principle of DNS consistency.

For new gTLD applicants, this fragmentation poses several risks. From a technical standpoint, alternate root collisions can lead to resolution failures, unexpected redirects, or user confusion, especially in environments where multiple root systems are accessible—such as mobile networks, corporate intranets, or state-operated ISPs. Registry operators whose strings are affected by such conflicts may face customer support issues, brand damage, and challenges in enforcing DNS-based policies or contractual obligations. For example, if a brand invests in .brand through the ICANN process but finds that the same string is being actively used in an alternate root to host unrelated or malicious content, the brand’s ability to control its identity and protect its customers online is diminished.

The political and legal dimensions of alternate roots add another layer of complexity. Some nation-states have begun promoting or developing alternate root infrastructures as part of broader digital sovereignty initiatives, asserting the right to define and manage domain names within their own jurisdictions independently of ICANN’s authority. While such efforts are often framed as efforts to protect local culture, language, or data policy preferences, they can also serve as mechanisms to circumvent global consensus-based governance or to assert control over online content and infrastructure. In these contexts, new gTLDs may find their reach limited or undermined in specific markets if alternate root usage becomes widespread or state-mandated.

From a market perspective, the presence of alternate roots introduces uncertainty for investors, registrars, and end users. Registry operators launching strings in the 2026 round must account for the possibility that the uniqueness and exclusivity they expect may not hold in every environment. This could influence premium pricing strategies, brand partnerships, and adoption efforts, particularly in countries or sectors where alternate root systems have gained traction. Registrars may also hesitate to promote or support TLDs that are known to conflict with alternate namespaces, especially if doing so increases operational complexity or exposes them to regulatory scrutiny.

To mitigate these challenges, ICANN and the broader internet governance community have emphasized the importance of root zone uniqueness and adherence to the IANA-managed root. The Root Zone Management system ensures that each delegated string is globally unique, coordinated, and technically interoperable with all compliant resolvers. ICANN’s agreements and technical safeguards require registry operators to avoid acting in ways that undermine this global interoperability, including participating in alternate root ecosystems that could conflict with the IANA root. Applicants to the 2026 round must commit to operating within this framework and may face denial of their applications or later compliance actions if found to be violating these principles.

Nonetheless, ICANN’s authority is based on voluntary cooperation, and there is no technical mechanism to prevent the creation or use of alternate roots. Therefore, coordination, outreach, and policy dialogue remain critical. ICANN must continue to engage with governments, technical communities, and private sector stakeholders to advocate for the benefits of a single, interoperable root and to clarify the risks associated with fragmentation. The Internet Engineering Task Force (IETF), regional internet registries (RIRs), and network operators also play key roles in maintaining DNS stability through consistent implementation of root zone trust anchors and resolver configurations.

For registry applicants in the 2026 round, awareness and strategic foresight are essential. Before submitting a gTLD application, prospective operators should research whether their proposed string has been used or is being promoted in alternate root systems. This includes checking known alternate root operators, scanning public DNS configurations, and engaging with regional internet communities to identify potential conflicts. If a string has known overlap with alternate root namespaces, applicants must assess the legal, technical, and reputational implications and determine whether the risk can be mitigated through public education, technical safeguards, or modified business strategies.

Additionally, brand protection strategies may need to evolve in light of alternate root activity. Trademark holders securing .brand TLDs in 2026 should consider proactive monitoring of alternate roots for potential infringements or impersonation. While enforcement options are limited in systems outside ICANN’s remit, public pressure, contractual leverage, and diplomatic channels may provide recourse in cases of egregious misuse. In extreme cases, DNS-based security tools such as DNSSEC, certificate transparency monitoring, and anti-phishing defenses may be employed to protect end users from harmful activity masquerading under a familiar TLD string.

Ultimately, alternate root implications for new gTLDs in 2026 are not purely technical or abstract—they are deeply connected to global internet governance, sovereignty debates, and the integrity of digital identity. While ICANN continues to steward a coordinated, consensus-driven DNS, new gTLD applicants must recognize that the internet’s landscape is shifting. Ensuring that their TLDs are both resilient and recognized in this evolving environment will require a combination of technical diligence, policy engagement, and strategic adaptability. The future of DNS may not rest solely on code or infrastructure, but on the shared commitment of global stakeholders to uphold the vision of a single, trusted, and universally accessible internet.
