About .icu

.icu is a generic top-level domain (gTLD) operated by Shortdot SA, a Luxembourg-based company. The domain was originally delegated in 2015 to One.com A/S before being transferred to Shortdot in 2018. While the letters "icu" are often interpreted as "I see you," the TLD has no formal restrictions on registration. It is open to anyone worldwide, making it a popular choice for personal websites, creative projects, and businesses looking for a short, memorable domain. The registry services are provided by CentralNic, and the domain uses a standard WHOIS and RDAP system. There are no eligibility requirements or usage limits, so individuals and organizations can register .icu domains freely. The TLD is managed under the oversight of ICANN and follows standard gTLD policies.

History

The .icu domain was delegated to One.com A/S on March 6, 2015. In February 2018, the sponsorship was transferred to Shortdot SA, which continues to operate the TLD today.
