Network trust

what's this?
RPKI hygiene: C how networks compare →
78.5% of checked blocks have valid RPKI ROA coverage (51 of 65)
Possible discrepancies (4)

These blocks are registered to AARNet 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.
