I'm curious, how does one go about obtaining IPv4 address space these days? I thought it had become quite a pain, and usually expensive enough to need serious cash?
Yeah, the auctions are about all I've seen and they're pricey enough one would probably need some investment or a substantial loan to obtain enough space for this sort of thing. I'm not sure how a trial hobby project gets the money for that.
No, because I may want it reachable from somewhere that doesn't have good v6 support. Plus this guy's project is literally based on v4, so I'm not sure how that would work.
