what's this?
RPKI hygiene: C how networks compare →
66.1% of checked blocks have valid RPKI ROA coverage (37 of 56)
Possible discrepancies (2)

These blocks are registered to DataWeb B.V. 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.
