Welcome to 1&1 IONOS

Tailored service with a personal consultant.

Who we are

1&1 IONOS is the web hosting and cloud partner for small and medium-sized businesses. We are experts in IaaS and offer a portfolio of solutions for the digital space. As the largest hosting company in Europe, we manage more than 8 million customer contracts and host over 12 million domains in our own regional data centers in the US and Europe.
We help entrepreneurs taking their first steps online, business owners scaling up, large companies, and the partners who help them succeed. Whether building an online presence by securing a domain, building a website, moving back-office processes to the cloud, or orchestrating a container cluster, our comprehensive product range offers a best-in-class app, server, or service.
Reliability and security are engineered into the core of our products. Our data center network delivers optimal performance and georedundancy. With headquarters in Germany, we rely on a solid mix of state-of-the-art technology, strong privacy policies, and airtight data security.
Customer service is paramount, which is why we offer a dedicated customer service agent to every customer. Your own personal consultant will take the time to get to know you and your business, helping you make the most of your online presence. World-class customer support through a single point of contact is yours at no extra cost.
You deserve nothing less than the latest technologies at a great price and in terms that are easy to understand. The best contract is flexible and doesn’t require a team of legal experts, so we’ve tried to make our product offerings and prices as transparent as possible. Helping to make you a success online is our gain—ensuring that you’ve got time for other more important things is our goal.

Our (hi)story

1&1 was born in 1988, with the main aim of making information technology easy for everyone to understand and use. Committed to delivering powerful, reliable, and secure products, 1&1 engineered its own data center architecture and extensive network, enabling millions of clients to get online, set up their web presence, and take advantage of more sophisticated digital services.
After initial successes in Europe, 1&1 launched 1&1 Inc. in 2003 in Chesterbrook, Pennsylvania. Within a year, 1&1 had expanded its US-based customer service team and in November 2004 the company ranked among the top ten web hosting providers in the United States. To better serve the market, a large data center of over 40,000 servers was commissioned in Lenexa, Kansas. 1&1 helped solidify its US market position by completing the takeover of mail.com in 2010.
Mass-market hosting success, combined with years of experience building server hardware tailored to cloud applications, was complemented by other strategic acquisitions to create a full-fledged hosting leader. 1&1 cemented its position as a world-class provider of hosting solutions and became the largest domain registrar in Europe.
Robust infrastructure portfolio in hand, 1&1 then integrated cloud-based digitization applications and tools into its offering, enabling businesses of any size to safely and simply harness the benefits of the cloud.

Becoming 1&1 IONOS

In 2018, to build upon its vision of empowering businesses to leverage the latest digital technologies, 1&1 combined its web hosting, applications, and server product lines with ProfitBricks’ cloud infrastructure solutions, becoming 1&1 IONOS and reaffirming its dedication to innovation and customer centricity.
Proud of its heritage, 1&1 IONOS will continue its mission: to make powerful technology work for everyone, and to deliver the best of cloud computing.
1&1 IONOS is a member of the United Internet group.
