What is a .io domain?
The .io domain is officially the country-code extension of the British Indian Ocean Territory, a group of islands in the Chagos Archipelago. In tech, though, "IO" means input/output, and that wordplay has turned .io into one of the most popular extensions for startups, developer tools, browser games and SaaS products.
Google treats .io as a generic extension rather than a geographic signal, so a .io site can target any market. One thing to watch: the 2024 agreement between the United Kingdom and Mauritius on sovereignty over the archipelago raised questions about the extension's long-term future, and any change would follow ICANN and IANA procedures. We host the DNS zone for free with a record editor, and renewals are taken automatically from your account credit.

Who a .io domain suits

- Online and browser-based ".io" games
- Teams whose name is taken on .com and want an alternative well known in tech
Registration rules for .io
- There is no residency requirement: anyone can register a .io
- Names use letters, digits and hyphens; the registry may reserve certain names or price them as premium
- The registry's acceptable use policies forbid using the domain for illegal or abusive activity
- Like any ccTLD, the extension depends on the territory's status; sovereignty changes could affect how it is run in the long term
Tips for choosing a .io name
- Use .io for technical products rather than local businesses: the general public recognises it less readily than .com
- Also take the .com of your name if it is free, so people who type another extension by reflex still find you
- Keep important names on more than one extension as a fallback in case of registry-level changes
- Start a cloud server with one-click Coolify or n8n and publish your app on subdomains (app, api, docs)

Questions about .io domains
Why is .io so popular with startups?
Because "IO" (input/output) is a term every developer knows, and short names are easier to find than on .com. The extension has become a signal that the product is technical. Many investors and tech users recognise it instantly.
What happens to .io after the Chagos agreement?
The agreement between the United Kingdom and Mauritius raised questions about the extension's status, since ccTLDs are tied to territories. Any change would go through ICANN and IANA procedures, which usually involve long transition periods. For critical projects it is prudent to hold another extension as well.
Does .io help SEO?
Google treats .io as a generic extension, so it is not tied to any country. It brings no direct ranking advantage but no penalty either: content, speed and links are what count. You can target any market through language and Search Console settings.
Can anyone register a .io?
Yes, the extension has no residency requirements, so individuals and companies anywhere can register one without extra documents. Contact details must be accurate and the domain must be used in line with the registry's rules.
How much does a .io domain cost?
Registering a .io domain costs €73.26 for the first year and €87.31 for each renewal, VAT excluded, paid from your account credit. There is no setup fee and DNS hosting is included.
For how long can I register a .io domain?
You can register a .io domain for 1 to 10 years at once. After that it renews automatically from your credit a month before expiry, and you get an email if your credit is short.
Can I transfer my .io domain to cloudlinux.ro?
Yes. Transferring a .io domain costs €73.26 and normally adds a year to its expiry. Unlock the domain at your current registrar, get the transfer code and start the transfer from the Domains section of your console.
Can I host a website on my .io domain with you?
Yes. Launch a cloud server billed by the hour, pick a one-click app such as WordPress, Ghost or Nextcloud, and point your .io domain to it from the DNS editor. The domain also works with any server you run elsewhere.
