The following was announced on July 18 on the 44-announce email listserver — Announcements regarding AMPRNet.
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 AMPRNet.
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 220.127.116.11 through 18.104.22.168 (in Internet notation, 22.214.171.124/8). Post-sale, it consists of addresses 126.96.36.199 through 188.8.131.52 (184.108.40.206/9 plus 220.127.116.11/10). The uppermost 1/4 of the former AMPRNet address space (18.104.22.168/10) has been withdrawn from ham radio use and sold to another owner, however over 12 million IPv4 addresses remain for amateur radio use.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.
