Well, I've known of it for 30 years. Since starting with AX.25 to a TNC, then playing with KA9Q NOS. So it isn't really a secret. As I understand it, the range was supposed to only be used for Ham to Ham comms, so if routed (generally tunneled) over the Internet, was only supposed to be to other Hams. Certainly there are people with ACLs expecting that 44.0.0.0/8 will never be sent to the Internet, nor received from the Internet. So it has in effect been a bit like a shared RFC1918 space, but for Hams alone. Moreover those in the know probably have it in their Bogon filers, I certainly do. So it may not yet be as usable as Amazon hope.
