⚠ 7 Préfixe MOASes — plusieurs ASN d'origine détectés

Toutes les anomalies MOAS →

Un préfixe auparavant stable, originaire de l'AS3561 est maintenant également annoncé par un autre ASN (MOAS — Multiple-Origin AS), détecté par nos collecteurs RIPE RIS. Souvent bénin (anycast, multi-homing, ou un transfert récent) — mais cela peut signaler une fuite de route ou un détournement de préfixe, il est donc utile de l'inspecter.
