RPKI hygiene: C how networks compare →
65.4% of checked blocks have valid RPKI ROA coverage (17 of 26)
Possible discrepancies (1)

These blocks are registered to CIS 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.
