Network trust

what's this?
RPKI hygiene: D how networks compare →
29.7% of checked blocks have valid RPKI ROA coverage (19 of 64)
Possible discrepancies (12)

These blocks are registered to SIN but cryptographically authorized for a different, unrelated network (2 distinct holders) — often M&A history, multi-homing, or outsourced/managed hosting, occasionally worth a closer look.
