A .IO domain is especially popular with startups, SaaS companies, developer tools, AI products, APIs, games, and other technology projects.
Although .IO is the country-code domain for the British Indian Ocean Territory, you do not need to live there to register one. The official .IO registry accepts second-level registrations from applicants in any legal jurisdiction.
Registration at NiceNIC is straightforward: search for an available name, enter accurate holder information, review the order, and complete payment.
You can check .IO availability and the current price at NiceNIC before starting.

Before You Register
Prepare:
Step 1: Search for Your .IO Domain
Go to the NiceNIC domain search page and enter the name you want, for example:
exampleapp.io
Click Search.
If the name is available, the search result displays the current registration price.
The example shown in this guide displays:
$49.99 / 1st year
Click Register to continue.
.IO has become widely associated with technology because “I/O” is a familiar abbreviation for “input/output” in computing. That makes the extension particularly recognizable for developer-focused products and technology brands.
Step 2: Enter the Domain Holder Information
NiceNIC next opens the registration contact page.
Enter the actual information of the individual or organization that will own the domain:
The official .IO rules require accurate and verifiable holder and administrative contact information, including a physical address and valid email address.
What About Nameservers?
NiceNIC automatically enters:
ns3.my-ndns.com
ns4.my-ndns.com
You can normally keep these unless your hosting or DNS provider has supplied different nameservers.
The official .IO rules require at least two nameservers for a second-level .IO domain. NiceNIC's two default nameservers already provide the values needed in the registration form, so there is no need to make this step complicated.
Accept the Domain Registration Service Agreement and click Next step.
Step 3: Review the Registration Details
The next page displays the information that will be submitted with your order.
Check:
.IO names are allocated on a first-come, first-served basis, so an available name is not secured until the registration is successfully completed.
Click Next when everything is correct.
Step 4: Check the Price and Complete Payment
The order page shows the domain, registration term, price, total amount, and current account balance.
The example order shown in this guide is:
Registration term: 1 year
Price: $49.99
Total amount: $49.99
Check the Renewal Cost Before Paying
For .IO, looking only at the first-year price can give an incomplete picture.
The current Market renewal price is $99.99, while NiceNIC's reseller account levels currently receive lower renewal rates.
If you plan to build a long-term startup, SaaS product, developer tool, or domain portfolio on .IO, compare both:
First-year registration price + future renewal price
before making your decision.
Click Pay by Crypto / PayPal to continue.
Review the final amount and any payment-provider fee before completing the transaction.
