Inside United Internet’s journey through telecom, hosting and internet services

United Internet traces its roots to 1&1 Marketing, founded by Ralph Dommermuth in Germany in 1988.

How United Internet developed

The company evolved from marketing technology services into internet access, web hosting and online applications, listed publicly in 1998 and took the United Internet name in 2000. Over time it built and acquired brands across broadband, mobile, hosting and consumer internet services.

United Internet in 2026

By 2026, United Internet operated a portfolio that included telecommunications and cloud or web services through businesses such as 1&1 and IONOS.

Its history shows how early internet-service companies could diversify into both connectivity and hosting, then reorganise those businesses as each reached sufficient scale.
