RPKI hygiene: A how networks compare →
96.8% of checked blocks have valid RPKI ROA coverage (1,936 of 2,000, sampled from 7,429)
Wholesale/transit re-announcements (16)

These blocks are registered to Cloudflare, Inc. but cryptographically authorized across 10 different networks — typical for a large wholesale or transit carrier whose address space is substantially re-announced by downstream customers under their own ASNs, not individually noteworthy.
