what's this?

RPKI hygiene: A how networks compare →

97.5% of checked blocks have valid RPKI ROA coverage (39 of 40)

Possible discrepancies (17)

These blocks are registered to Yang Liuchang 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.
