Network trust

what's this?
RPKI hygiene: A how networks compare →
98.9% of checked blocks have valid RPKI ROA coverage (87 of 88)
Possible discrepancies (10)

These blocks are registered to IS-BASIS-NET 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.
