what's this?
RPKI hygiene: B how networks compare →
92.1% of checked blocks have valid RPKI ROA coverage (70 of 76)
Possible discrepancies (3)

These blocks are registered to MCS LLC 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.
