Network trust

what's this?
RPKI hygiene: D how networks compare →
45.6% of checked blocks have valid RPKI ROA coverage (72 of 158)
Wholesale/transit re-announcements (72)

These blocks are registered to NICSIDC 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.
