what's this?
RPKI hygiene: C how networks compare →
59.2% of checked blocks have valid RPKI ROA coverage (42 of 71)
Possible discrepancies (17)

These blocks are registered to ULTRA ONE 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.
