IPv4 allocation over time
Cumulative IPv4 address space handed out worldwide, by allocation date.
IPv6 allocation over time
Cumulative IPv6 space (in /48 equivalents). Note the very different scale.
Autonomous System Numbers
Growth of the routed Internet over time, and which countries run the most networks.

Where the IPv4 space went
All 2³² IPv4 addresses, split by how they're used: allocated to RIRs, reserved for special purposes, or still unallocated.
Dark IPv4 — allocated but unrouted
Address space that's been handed out but isn't visible in the global routing table — held in reserve, used privately, or simply idle.
Routing table
The shape of the global BGP table: how many prefixes are announced, and how fragmented IPv4 has become.
