Resolve ASN & Abuse Contacts
Fastest path: load the WhoisXML IP Netblocks and resolve ASN/org/country locally (millions/sec, no API). Then pull abuse contacts for every ASN from RIPEstat. 69 ASN abuse contacts cached.
▶ Resolve ASN from local data
▶ Resolve abuse contacts (RIPEstat)
Resolve 50 via ipinfo (needs outbound)

Worst ASNs by Targeting Priority
Priority = malicious IP count × average threat. High-priority ASNs concentrate the most malicious infrastructure — the best candidates for block-listing at the network level or coordinated takedown.

Targeting Recommendations
- ■ AS4134 (China Telecom) is your #1 target — 44 malicious IPs concentrated here.
- ■ 12 ASNs carry 10+ malicious IPs each — network-level blocking of these gives the highest coverage-per-rule.
- ■ For coordinated takedown, start with high-priority ASNs whose dominant activity is Ransomware or C2 / APT — the highest-impact classes.
- ■ Use the Takedown Ops tool to pull abuse contacts for the network operators above.
