⚠ 1 MOAS prefix — meerdere origin ASNs gedetecteerd

Alle MOAS-anomalieën →

Een voorheen stabiele prefix afkomstig van AS1501 wordt nu ook aangekondigd door een andere ASN (MOAS — Multiple-Origin AS), gedetecteerd door onze RIPE RIS-collectoren. Vaak goedaardig (anycast, multi-homing of een recente overdracht) — maar het kan duiden op een route leak of prefix hijack, dus het is de moeite waard om te onderzoeken.
