⚠ 1 MOAS prefix — multiple origin ASNs detected

All MOAS anomalies →

A previously stable prefix originated by AS133774 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.

Prefix	Origin ASNs	Last detected (UTC)
27.0.132.0/22	AS58854, AS133774	2026-11-14 20:39:21

Web3 footprint

AS133774 hosts 2 observed decentralized-network nodes across 2 networks. It’s a neutral signal — it does not affect the reputation score. See the full web3 node map.
