.blue domain extension

.blue is a generic top-level domain open to anyone. It was created for websites, brands, and communities that want to associate themselves with the color blue. That could mean anything from a company with a blue logo to a fan site for a sports team that wears blue. The domain is run by Identity Digital Limited, a large registry operator based in the United States. There are no special eligibility rules. Anyone can register a .blue domain through any accredited registrar. The domain was delegated in January 2014, originally to Afilias Limited. Identity Digital later took over as the sponsoring organization. The registry uses standard name servers and supports RDAP for domain lookups. If you need a short, memorable web address that signals something blue, this TLD is a straightforward choice.

The .blue domain was delegated to Afilias Limited on January 29, 2014. It was one of several new generic TLDs introduced in ICANN's new gTLD program. Identity Digital Limited later became the sponsoring organization, and the record was last updated in September 2025.
