Network trust

what's this?
RPKI hygiene: A how networks compare →
98.5% of checked blocks have valid RPKI ROA coverage (65 of 66)
Possible discrepancies (65)

These blocks are registered to CERNET2 IX at Jilin University 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.
