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
- Long-established allocation (25y) +6
- Not on any threat blocklist +5
- Has a reverse-DNS (PTR) record +5
- Isp allocation +5
- Trust score 86 / 100
