what's this?
RPKI hygiene: A how networks compare →
100.0% of checked blocks have valid RPKI ROA coverage (9 of 9)
Possible discrepancies (1)

These blocks are registered to DERBY-NET 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.

212.142.22.0/24 /24 authorized for AS6830 — Liberty Global Europe Holding B.V.
Routed via provider/NREN (6)

These blocks are cryptographically authorized for this organisation's national research & education network or transit provider — expected topology for an institution that routes through it, not a discrepancy.
