⚠ 11 Prefijo MOASes — múltiples ASNs de origen detectados
Todas las anomalías MOAS →Un prefijo previamente estable originado por AS2 es ahora también anunciado por otro ASN (MOAS — Multiple-Origin AS), detectado por nuestros colectores RIPE RIS. A menudo es benigno (anycast, multi-homing o una transferencia reciente), pero puede indicar una fuga de ruta o un secuestro de prefijo, por lo que vale la pena investigarlo.
