⚠ 39 MOAS-Präfixes — mehrere Origin-ASNs erkannt

Alle MOAS-Anomalien →

Ein zuvor stabiles Präfix, das von AS33651 wird jetzt auch von einer anderen ASN angekündigt (MOAS — Multiple-Origin AS), erkannt von unseren RIPE RIS Kollektoren. Oft harmlos (Anycast, Multi-Homing oder eine kürzliche Übertragung) — aber es kann ein Route Leak oder Prefix Hijack signalisieren, daher ist eine Überprüfung sinnvoll.
