RPKI hygiene: A how networks compare →
100.0% of checked blocks have valid RPKI ROA coverage (88 of 88)
Possible discrepancies (8)

These blocks are registered to CZ-MNET 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.
