Network trust

what's this?
RPKI hygiene: B how networks compare →
94.7% of checked blocks have valid RPKI ROA coverage (503 of 531)
Possible discrepancies (3)

These blocks are registered to NTTCINS but cryptographically authorized for a different, unrelated network (2 distinct holders) — often M&A history, multi-homing, or outsourced/managed hosting, occasionally worth a closer look.
