All 2³² IPv4 addresses, split by how they're used: allocated to RIRs, reserved for special purposes, or still unallocated.
Address space that's been handed out but isn't visible in the global routing table — held in reserve, used privately, or simply idle.
The shape of the global BGP table: how many prefixes are announced, and how fragmented IPv4 has become.
Record holders and notable milestones — plus what was allocated on this day in years past.
