what's this?
RPKI hygiene: C how networks compare →
77.6% of checked blocks have valid RPKI ROA coverage (132 of 170)
Possible discrepancies (4)

These blocks are registered to ISIF OU 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.
