- Amateur Radio Digital Communications [ARDC] is a United States
- charitable 501(c)(3) nonprofit public benefit corporation that has
- long owned and managed the Internet address space known as the
- Nearly 40 years ago, early in the evolution of the Internet, this
- address allocation was acquired to be used for the mutual benefit
- of Amateur Radio and digital communications technology.
- Amateur Radio operators ("hams") use the global radio spectrum set
- aside for them by international treaty in non-commercial ways to
- improve engineering, research, experimentation, training, education,
- and emergency communications. Having the AMPRNet available over
- the past four decades has facilitated integration of the Internet
- with radio-based technologies long used by hams. This long term
- interaction has been key to development of now ubiquitous wireless
- technology such as WiFi and the ability to browse the Internet or
- to stream various media to your mobile phone.
- Over those past decades, a portion of the AMPRNet IPv4 address space
- has rarely been used, and recent utilization surveys show that it
- is not likely to ever be needed by hams.
- Initially free, IPv4 Internet addresses are now highly valuable,
- and there is an international marketplace in which to sell them.
- ARDC has sold some of its unused and unneeded address space, but
- retains a more than ample supply of IPv4 addresses for current and
- future use by the many Amateur Radio operators worldwide. The sale
- amounts to some millions of dollars, which will be used in the
- furtherance of ARDC's continuing public benefit purpose.
- Before the sale, the AMPRNet consisted of the addresses 22.214.171.124
- through 126.96.36.199 (in Internet notation, 188.8.131.52/8). Post-sale,
- it consists of addresses 184.108.40.206 through 220.127.116.11 (18.104.22.168/9
- plus 22.214.171.124/10). The uppermost 1/4 of the former AMPRNet address
- space (126.96.36.199/10) has been withdrawn from ham radio use and
- sold to another owner, however over 12 million IPv4 addresses remain
- for amateur radio use.
- ARDC will use the proceeds of this address sale to further its
- mission to support, promote, and enhance Amateur Radio, digital
- communications, and broader communication science and technology
- by funding grants and scholarships for scientific research,
- experimentation, education, open access, and innovation in information
- and communications technology, with an emphasis on benefiting the
- international Amateur Radio service.
