.io Domain: Risks and Future

The .io domain has become a favorite among startups, developers, and tech companies worldwide thanks to its short, tech-friendly appearance. But its future may be at risk: geopolitical changes could lead to the phasing out or reassignment of this popular TLD in the coming years.

What’s behind this development? And what does it mean for businesses using .io domains?

Background: The End of the British Indian Ocean Territory (BIOT)

The .io domain is a country-code top-level domain (ccTLD) originally assigned in 1997 to the British Indian Ocean Territory (BIOT) – a disputed overseas territory of the UK in the Indian Ocean.

Following international pressure and a ruling by the International Court of Justice in 2021, the UK officially agreed in 2025 to return the territory to Mauritius. This political shift threatens the ISO country code “IO” – the foundation of the .io domain.

Why This Affects the Domain

ccTLDs are based on official country codes listed in the ISO 3166 standard. If the code “IO” is removed, the .io domain would lose its status as a country-specific extension.

This could trigger action by the Internet Assigned Numbers Authority (IANA), which may begin a multiyear decommissioning process. Typically, this would unfold over 5–10 years, allowing existing domains to expire and halting new registrations.

Status Update (Summer 2025)

  • In May 2025, the UK and Mauritius signed the agreement to transfer the BIOT.
  • The ISO has not yet officially removed the “IO” code.
  • The .io domain remains fully functional, with new registrations still possible.
  • The domain registry is still operated by Identity Digital.

Possible Future Scenarios

Scenario 1: Gradual Phase-Out

If ISO removes the “IO” code, IANA may begin decommissioning. Existing domains would remain active for years, but no new registrations would be allowed. Full removal could happen in the 2030s.

Scenario 2: Continued Operation Under Mauritius

Mauritius could take over the domain officially and negotiate with ICANN or the current registry to keep it active under new management or a joint arrangement.

Scenario 3: Reclassification as a gTLD

ICANN could convert .io into a generic top-level domain (gTLD) like .com or .tech. This would decouple it from the BIOT entirely, but the process would be complex and rare.

Scenario 4: “Exceptionally Reserved” Status

The ISO could place “IO” on an exceptional reserved list (as done with .su for the Soviet Union), allowing .io to continue despite the territory’s end.

Risks for Businesses and Domain Owners

While no immediate shutdown is planned, companies should be aware of potential medium-term risks:

  • SEO impact if a domain migration becomes necessary.
  • Customer trust issues due to perceived instability.
  • Legal uncertainty around commercial use.
  • Branding challenges for those heavily invested in the .io identity.

What You Can Do Now

1. Prepare for Uncertainty

Plan ahead. If your project has a long lifespan, consider alternatives or backup options.

2. Register Alternative Domains

Secure relevant domains like .com, .tech, .dev, .ai, or a local ccTLD. CURIAWEB GmbH can help you with strategic domain selection and registration.

3. Set Up Redirects

If you already own alternative domains, set up redirects to keep traffic centralized and prepare for a smooth transition later if needed.

4. Review Your Infrastructure

Ensure your email systems, SSL certificates, and application configurations can handle a domain switch with minimal disruption.

5. Follow Ongoing Developments

Stay updated via trusted sources like ICANN, IANA, or your domain partner – such as CURIAWEB GmbH.

Conclusion: .io Still Stable – but the Future Is Uncertain

There’s no need to panic for now – the .io domain remains functional. But its long-term future is uncertain due to legal and geopolitical shifts.

The smartest move? Be prepared, secure your backups, and follow the news closely.
