Network trust

what's this?
RPKI hygiene: D how networks compare →
33.3% of checked blocks have valid RPKI ROA coverage (19 of 57)
Possible discrepancies (1)

These blocks are registered to NetCologne GmbH but cryptographically authorized for a different, unrelated network (1 distinct holder) — often M&A history, multi-homing, or outsourced/managed hosting, occasionally worth a closer look.
