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

⚠ 34 MOAS 前缀es — 检测到多源 ASNs
所有 MOAS 异常 →此前由 AS3257 公告的稳定前缀现在也由另一个 ASN 公告（MOAS — 多源 AS），这是通过我们的 RIPE RIS 收集器检测到的。这通常是良性的（任播、多宿主或近期转移）—— 但它可能预示着路由泄漏或前缀劫持，因此值得检查。
