Network trust

what's this?
RPKI hygiene: A how networks compare →
98.9% of checked blocks have valid RPKI ROA coverage (90 of 91)
Possible discrepancies (81)

These blocks are registered to Cablemodem but cryptographically authorized for a different, unrelated network (3 distinct holders) — often M&A history, multi-homing, or outsourced/managed hosting, occasionally worth a closer look.
