what's this?
RPKI hygiene: F how networks compare →
14.7% of checked blocks have valid RPKI ROA coverage (5 of 34)
Possible discrepancies (5)

These blocks are registered to CTTNET 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.
