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 (18y) +6
• Not on any threat blocklist +5
• Trust score 76 / 100
