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. 0 ASN abuse contacts cached.

▶ Resolve ASN from local data ▶ Resolve abuse contacts (RIPEstat) Resolve 50 via ipinfo (needs outbound) ↻ Recompute ranking Export abuse contacts (CSV)

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 (unknown org) is your #1 target — 42 malicious IPs concentrated here.
  • ■ 8 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.
