⚠ 2 MOAS prefixes — multiple origin ASNs detected

All MOAS anomalies →

A previously stable prefix originated by AS12200 is now also announced by another ASN (MOAS — Multiple-Origin AS), detected from our RIPE RIS collectors. Often benign (anycast, multi-homing, or a recent transfer) — but it can signal a route leak or prefix hijack, so it's worth inspecting.
