Not only popular with tech startups
Why register a .io domain?
Although the .io domain names have been around as early as 1997, it is still less occupied than other generic and extremely popular top-level domains (TLDs). The .io country code domains are an attractive option amongst the tech and startup scene and this is largely due to the fact that the letters stand for input/output within the industry.
Input/output represents the fundamental concept of computers: every input results in an output. Businesses, companies and individuals alike can benefit from the creative freedom of choosing their favoured domain name; a meaningful, unique and concise name may be what it takes to position your business ahead of the competition.

Getting a .io domain with IONOS couldn't be any easier. Simply enter your desired web address in the search bar and with just the click of a mouse, you'll find out if it is still available. If so, you can buy your .io domain directly, easily and cheaply. Our tip: make sure you get the domain you want before someone else does. Otherwise, it may already be taken, and can only be acquired if the website owner violates your name or trademark rights. At worst, this will then require litigation. All of this can be avoided by securing your .io domain early.
As soon as you have checked if your .io domain is available, you can also check if there are other domains available that you are interested in. You will automatically receive suggestions for additional domain names or top-level domains that may not have crossed your mind yet, but which may also be of interest to you. If this is the case, you can also place the corresponding domains in your shopping cart, and complete the purchase.
