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
- Forward-confirmed reverse DNS (FCrDNS) +10
- Long-established allocation (21y) +6
- Not on any threat blocklist +5
