Talk 1: net44 – An under-utilised resource or potential fun? (Postponed)

44.0.0.0/8 was allocated in 1992 for amateur radio. Before the rise of the internet hamradio enthusiasts used low 1200bps and 9600bps unlicensed link to form mesh networks. In recent years this has dwindled away, now those left using the resource have IPIP tunnels normally back to California.

In 2015 the net44 rules were relaxed, allowing participants to announce their own subnets with BGP.

I’ll discuss how easy it is to obtain a UK ham radio license and the simple AMPRnet application process to get your own free /24, which could be announced by an ISP or hosting provider such as Vultr/Mythic Beasts etc.
