What are .org domains?

Short for "organization," .org is one of the seven original "generic" Top Level Domains (TLDs). It is currently the Internet's fifth largest TLD, with over two million registrations worldwide. The .org domain was originally intended as a "miscellaneous" TLD for educational institutions, network providers, governmental agencies or organizations that weren't commercial entities. In recent years, registration in .org has become open and unrestricted.
