.adult

.adult is a generic top-level domain with an explicitly adult-oriented meaning. It is a non-sponsored gTLD under an ICANN registry agreement, so the extension itself is not limited to a membership organization or professional category.

The clearest use is for websites and services that deliberately want an adult identity to be obvious in the address. That can help separate adult-oriented material from a broader corporate or personal web presence, and it may also matter to organizations considering defensive registrations around sensitive brand terms.

The domain ending does not authorize any particular content or business model. Operators remain responsible for laws and rules concerning age restrictions, consent, intellectual property, privacy, payment processing, advertising and content distribution in every market where the service is offered.

Because the meaning is so strong, .adult is a poor fit when a project needs a neutral, family-facing or broadly corporate identity. The reputational effect of the extension should be considered before using it as a primary brand domain.

Registration is generally available through participating registrars, subject to registry and ICANN policies, reserved names and applicable legal rights.
