⚠ 33 Prefixo MOASes — múltiplos ASNs de origem detectados

Todas as anomalias MOAS →

Um prefixo anteriormente estável originado por AS33667 é agora também anunciado por outro ASN (MOAS — Multiple-Origin AS), detectado a partir de nossos coletores RIPE RIS. Frequentemente benigno (anycast, multi-homing ou uma transferência recente) — mas pode sinalizar um vazamento de rota ou sequestro de prefixo, então vale a pena inspecionar.
