Network trust

what's this?
RPKI hygiene: A how networks compare →
100.0% of checked blocks have valid RPKI ROA coverage (74 of 74)
Possible discrepancies (2)

These blocks are registered to CTC_CLIENTS 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.
