One place for the Internet's extremes — the biggest networks, the most-fragmented routing, the largest hoards of unused (dark) IPv4, RPKI leaders and laggards, the busiest transfer-market players, the largest transit cones, the most-connected networks, and the noisiest origins on routing security and hygiene. Every leaderboard is rebuilt daily from the RIRs, CAIDA, PeeringDB and RPKI data.
The ASes holding the most routed IPv4 address space.

The ASes announcing the most distinct BGP prefixes into the global table.
Prefixes announced per million IPv4 addresses held — deaggregation leaders (≥ 65,536 addrs).
The biggest transit networks by CAIDA customer-cone size — how many ASes sit downstream of each.
Countries with the highest valid share (routed IPv4 ≥ 10M addresses).

Networks announcing the most RPKI-invalid IPv4 — the biggest potential hijacks or misconfigurations.
Economies holding huge IPv6 allocations but with little measured deployment — the biggest rank gap between holdings and reality.
