Network trust

what's this?
RPKI hygiene: B how networks compare →
90.0% of checked blocks have valid RPKI ROA coverage (36 of 40)
Possible discrepancies (34)

These blocks are registered to SDC Internet 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.
