what's this?
RPKI hygiene: B how networks compare →
88.1% of checked blocks have valid RPKI ROA coverage (59 of 67)
Possible discrepancies (1)

These blocks are registered to CEMEX but cryptographically authorized for a different, unrelated network (1 distinct holder) — often M&A history, multi-homing, or outsourced/managed hosting, occasionally worth a closer look.
