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

⚠ 17 Prefijo MOASes — múltiples ASNs de origen detectados
Todas las anomalías MOAS →Un prefijo previamente estable originado por AS1637 es ahora también anunciado por otro ASN (MOAS — Multiple-Origin AS), detectado por nuestros colectores RIPE RIS. A menudo es benigno (anycast, multi-homing o una transferencia reciente), pero puede indicar una fuga de ruta o un secuestro de prefijo, por lo que vale la pena investigarlo.
