Many years ago I remember reading about the upcoming implementation of the internet protocol IPv6 - which is now in place. In that article it mentioned that there was some discussion about space - I mean outer space, not namespace. At the time, it seemed that the author was not just speculating, but that they were actually referring to some plans or at least calculations.
I'm not asking about private networks, or ESA or NASA networks. I'm asking about the "normal internet" that we all (well, most of us) can use.
note: This question is about the internet, not internet access. Put in terrestrial terms, I'm not asking about the WiFi vs 4G access to a router, I'm asking about the router's connection to the rest of the routers - the internet.
