The .ONG domain extension is primarily associated with non-governmental organizations (NGOs) and is used as an alternative to the more common .ORG extension. It stands for "Organización No Gubernamental" in Spanish, which translates to "Non-Governmental Organization" in English.

The .ONG extension serves as a recognizable marker for organizations dedicated to social causes, humanitarian efforts, environmental conservation, advocacy, and other charitable activities. It offers a distinct online identity for NGOs seeking to establish their presence on the internet.

The .ONG domain extension is suitable for a wide range of organizations, including established NGOs, grassroots movements, charitable foundations, advocacy groups, and community initiatives.

It offers a platform for these entities to showcase their work, raise awareness about social issues, mobilize support, and connect with stakeholders globally. 

Whether operating at a local, national, or international level, organizations seeking to amplify their impact, foster collaboration, and engage with supporters online can benefit from using the .ONG domain extension.
