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
- Active-threat / abuse risk −12
- Enterprise allocation +4
- Trust score 57 / 100

⚠ 2 MOAS prefixes — multiple origin ASNs detected
All MOAS anomalies →A previously stable prefix originated by AS1653 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) |
|---|---|---|
| 145.98.16.0/24 | AS1103, AS1653 | 2026-11-07 11:38:15 |
| 192.36.171.0/24 | AS1653, AS2603 | 2026-11-05 21:38:00 |
Web3 footprint
AS1653 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.
