Why choose a .io domain name?

With a .io domain name, you’re able to show deep-level tech know-how right from the URL. Why? Because the .io domain extension can stand for i/o, or input/output – very popular in the world of technology. That’s why everyone from startups to coders is getting in on the .io action.

What is a .io domain?

The original .io domain meaning isn’t actually connected to technology. It was created for the British Indian Ocean region, which covers over 2,300 small islands. This exotic heritage has since been hijacked by the tech community, because the .io domain name fits the world of digital innovation so perfectly.

Anyone can register a .io TLD

.io TLD and second-level domain extensions are open to people everywhere. Restrictions only apply to third-level subdomain .io names – available exclusively to British Indian Ocean residents. So, you can still get your perfect .io domains, and get your business growing.

Most frequently asked questions:

  1. When did tech professionals start using .io?

    Seeing the potential of .io as a tech-conscious, feature-leaning prefix for IT domains, tech professionals began snapping up these TLDs back in the late ‘90s. Now, as the digital world begins to dominate just about everything, the popularity is growing more rapidly.

  2. What else do I get with a .io domain?

    Like all other Namecheap domains, it's backed by our stellar service, plenty of free extras, and world-class support. Why wait? Register your .io domain today. Given that .io is just starting to get popular, there’s never been a better time to register the .io domain name.

  3. Are there any other restrictions?

    Per registry regulations, no .io domain may be used, directly or indirectly, for any purpose that is sexual or pornographic in nature, or violates the statutory laws of any nation. In the event that a specific site breaches this condition, the NIC.IO registry reserves the right to immediately deactivate the domain. The applicant may seek the reinstatement of any suspended domain name by requesting an arbitrator appointed by the World Intellectual Property organization.
