Reputation · trust score
A transparent 0–100 signal. Every entity starts at a neutral baseline of 65; threat-intel blocklists, exposure, reverse-DNS, routing and allocation each adjust it up or down. Higher is more trustworthy.
- Baseline (neutral) 65
- Multiple-origin (MOAS) routing anomaly −12

About ICANN
The Internet Corporation for Assigned Names and Numbers is a global multistakeholder group and nonprofit organization headquartered in the United States, responsible for coordinating the maintenance and procedures of several databases related to the namespaces and numerical spaces of the Internet, while also ensuring the Internet's smooth, secure, and stable operation. ICANN performs the actual technical maintenance (work) of the Central Internet Address pools and DNS root zone registries pursuant to the Internet Assigned Numbers Authority (IANA) function contract.
⚠ 1 MOAS prefix — multiple origin ASNs detected
All MOAS anomalies →A previously stable prefix originated by AS40528 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.
