what's this?
RPKI hygiene: A how networks compare →
97.7% of checked blocks have valid RPKI ROA coverage (631 of 646)
Possible discrepancies (4)

These blocks are registered to MASTER S/A 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.
