RPKI hygiene: A how networks compare →
100.0% of checked blocks have valid RPKI ROA coverage (75 of 75)
Wholesale/transit re-announcements (24)

These blocks are registered to FSTcloud 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.
