ARDC

Amateur Radio Digital Communications (ARDC) is a California-based foundation that owns the AMPRNet, also known as 44Net (44.0.0.0/9 and 44.128.0.0/10). It was formed to encourage and foster the development of amateur radio digital networking. You may contact ARDC by sending email to contact@ardc.org.

Note that ARDC is not an internet service provider. It does not provide any networking access or facilities. It manages and allocates subnets of 44Net (AMPRNet), to interested amateur radio operators. Persons who obtain an allocation of address space on 44Net must make their own arrangements for connectivity and internet service.

ARDC also grants funding to organizations that support, promote, and enhance amateur radio, digital communication and broader communication science and technology, education, development, open access, and innovation in information and communication technology.
