RPKI hygiene: D how networks compare →
45.3% of checked blocks have valid RPKI ROA coverage (121 of 267)
Possible discrepancies (10)

These blocks are registered to Siemens AG 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.
