RPKI hygiene: D how networks compare →
47.3% of checked blocks have valid RPKI ROA coverage (52 of 110)
Possible discrepancies (50)

These blocks are registered to CTHKI-HK but cryptographically authorized for a different, unrelated network (4 distinct holders) — often M&A history, multi-homing, or outsourced/managed hosting, occasionally worth a closer look.
