what's this?
RPKI hygiene: C how networks compare →
73.1% of checked blocks have valid RPKI ROA coverage (38 of 52)
Possible discrepancies (7)

These blocks are registered to Cloud Sigma 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.
