@Zergling_man @wolf480pl @Mamako The problem of IPv4 address exhaustion was not necessarily caused by demon rectangles - as pretty much all of them use IPv6 now...except with only a IPv4 gateway to the internet of course (but it's what 1 IPv4 address to tens of thousands of mobiles?).

There are now enough computers and servers on the internet that there are no more IPv4 blocks left to allocate and only the scraps remain.
