can I buy one ipv4 for myself somehow. not lease or rent, buy ?
I also don't think there are many places willing to announce your ultra specific route because it's not great for routing tables.
You can also acquire and use a /24 out of a class A or B block, thanks to this newfangled thing called CIDR. ;)
Thats what I have in my RIPE Account.
I could request a /32, but a /48 is definitely enough for me. Might request a second /48 at some point maybe.
