PSA that if you have a ham radio licence, anywhere in the world, there are IPv4 addresses available for you for the taking at ARDC (AMPR)[1].
You can either get a block of /24 to announce yourself (you've got to cover all the technical setup and costs of this) or use their free 44net.connect service and just organise a wireguard tunnel.
You cannot use it for anything commercial.
But in many countries (including Germany), you are not allowed to encrypt your transmissions via ham radio, e.g. using TLS with such IPv4 addresses is against the law.
I have looked into acquiring an ipv4 block many times but never came across this. Thanks for the lead!
Ok so I was looking at the market rates for ipv4, and it appears that $20 per IP is a common figure, which means that a /24 block is worth about $5000.. so, what's the catch? And how many /24 blocks does ARDC have available, really?
I'm most curious to understand why didn't bad actors gobble up all those /24 blocks already.
