About .htc domains

.HTC is a generic top-level domain (gTLD) delegated in the DNS root zone. The registry operator responsible for .HTC is listed by IANA as the contracted registry operator. Anyone can typically register a .HTC name through an accredited registrar, subject to the registry’s registration policy and ICANN consensus policies.

HTML Components (HTCs) are a legacy technology used to implement components in script as Dynamic HTML (DHTML) "behaviors" in the Microsoft Internet Explorer web browser. Such files typically use an .htc extension and the "text/x-component" MIME type. An HTC is typically an HTML file (with JScript / VBScript) and a set of elements that define the component. This helps to organize behavior encapsulated in script modules that can be attached to parts of a Webpage DOM.

Who can register .htc domains?

Eligibility is defined by the registry operator and its registrars. Most gTLDs are open to anyone worldwide. Many ccTLDs are also open globally; some require local presence, citizenship, or trademark rights. Always confirm current policy with the registry or your registrar.
