Network trust

what's this?
RPKI hygiene: C how networks compare →
61.9% of checked blocks have valid RPKI ROA coverage (78 of 126)
Wholesale/transit re-announcements (33)

These blocks are registered to System NET Line but cryptographically authorized across 6 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.
