what's this?
RPKI hygiene: D how networks compare →
42.0% of checked blocks have valid RPKI ROA coverage (21 of 50)
Possible discrepancies (2)

These blocks are registered to ARM Ltd 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.
