RPKI hygiene: B how networks compare →
81.5% of checked blocks have valid RPKI ROA coverage (22 of 27)
Possible discrepancies (2)

These blocks are registered to IBH connect GmbH 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.

2a0c:2c0:dd80::/44 /44 authorized for AS203592 — CLOUD & HEAT Technologies GmbH
188.239.190.0/24 /24 authorized for AS20676 — Plusnet GmbH
Routed via provider/NREN (1)

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.
