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.
