What can a .io domain do for you?
If you’re a tech company or startup looking for a domain, then registering a .io domain makes a lot of sense. It’ll show prospective clients who you are and what you’re about.
Originally a country code for the British Indian Ocean Territories, .io has since become a short, snappy domain that can be used by anyone. With high availability and no clunky spelling, a .io domain is the perfect choice for a unique project.
You’ll find .io domains all over tech projects, online games and more. Commonly standing for input/output, it’s a popular choice for organisations with a technical offering and is recognised as the go-to domain for startups and side hustles.
When you use a .io domain name, you’ll have a name that’s new, exciting and shows that you’re a brand that strives to be at the forefront of technological advances – and that’s got to be a good thing if you’re a tech company yourself!
How to choose a .io domain name
Struggling to decide on the best .io domain name? We’ve got some top tips to make your website stand out.
Size does matter
While your .io domain name can be up to 63 characters, shorter ones are easier to remember and harder to misspell.
Steer clear of numbers
Using numbers in your domain name can be confusing. If you need to, consider registering a domain for each format.
Keep it simple
A domain name is the first thing people see when they find your site. Keep your .io domain short, sweet, and easy to type.
Avoid special characters
Avoid characters like exclamation marks and underscores. And if you need to use a hyphen, don’t put it first or last.

Frequently asked questions
What is a domain name?
A domain name is how people find you online. Websites are hosted on a web server, and domain names tell search engines and browsers where your site is hosted. Every domain has to be unique so that the web server knows where to point a user to.
What is a domain extension?
What is a subdomain?
If you want, you can add a shop to your website, for example, you can create a subdomain (e.g. shop.example.io). Did you know that with us you can have unlimited subdomains? So, make as many as your heart desires.
Is .io domain registration difficult?
It's super easy to register new domain names. All you have to do to find your perfect domain is use our availability checker. Simply search for an available domain name, enter some details, and you're good to go.
I already have a .io domain, can I transfer to Fasthosts?
Not to worry. Moving your domain name over to Fasthosts is easy, quick, and completely free. Head on over to our domain transfers page to find out more.
Can you help me find the perfect .io domain?
When you're choosing a domain name for your business, keep in mind the following:
- Protect your brand and register similar extensions (e.g. get a .io alongside .co.uk or .com domain name).
- With the onset of social media apps like Twitter and Facebook, it's a good idea to match domain names with your social media handles.
- Keep it simple. Names that are long or hard-to-spell could lead potential visitors to the wrong website or a 404 page. Shorter names are much easier to remember, and will make it easier for customers to find you.
Can I sell my .io domain name?
When you use Fasthosts, we give you full access to your DNS records (domain name system), which makes it as easy as possible to transfer your domain name, including to other people. So, if you want to sell your .io domain name, you can!
Why do I need a domain?
Your domain name is a key part of your website. A .io domain name that is uniquely your own is an identity on the internet, so search engines know where to send people who may be looking for you.
Who is a .io domain for?
A .io domain is perfect for any company that deals in tech, or just fancies cleverly ending their domain. Whether you’re a fun-loving moustache brand (moustach.io) or want a tech-related domain, .io can work for you in many ways.
Is a .io domain legit?
If you’re not familiar with the different TLDs that are out there, then you might be wary of anything that’s not the usual .com or .co.uk. But, as long as you choose a domain name through a reliable ICANN-accredited provider – and one that offers SSL certificates for your websites – then .io is a perfectly safe choice for a domain!
Do .io domains rank well?
Your TLD of choice is unlikely to impact the ranking of your website. As long as you have a well optimised website and high quality content, then any site with any TLD can rank highly on search engines!
