RPKI hygiene: C how networks compare →
60.8% of checked blocks have valid RPKI ROA coverage (45 of 74)
Wholesale/transit re-announcements (20)

These blocks are registered to DNS LLC but cryptographically authorized across 7 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.
