What Is ASN Reputation?

ASN reputation assesses how trustworthy a whole network is — based on the threat activity observed across the prefixes it routes, not just a single blocklist hit.

How Whisper models it

ASN—ROUTES→ANNOUNCED_PREFIX—LISTED_IN→FEED_SOURCE

Reputation is a rollup: an ASN inherits the threat density of everything it routes, so the listings across its prefixes aggregate to the network.

MATCH (a:ASN {name:"AS13335"})-[:ROUTES]->(p:ANNOUNCED_PREFIX) RETURN count(p) AS prefixes

A single bad IP tells you little; a network where many routed prefixes are threat-listed tells you a lot. ASN reputation rolls per-prefix threat signals up to the autonomous system, helping you spot bulletproof hosting and abuse-friendly networks.

WhisperGraph computes aggregate threat properties on each `ASN` — an overall threat level and max/average scores across its prefixes. Richer network-science reputation (AS rank, customer-cone size, peering centrality) is on the roadmap.
