IP Threat Intelligence & Abuse Management
Enrich security workflows with real-time IP reputation, privacy detection, and abuse contact data
Malicious actors hide behind VPNs, proxies, and Tor exit nodes while abusing IP addresses for spam, DDoS, and credential stuffing. EdgeDNS provides comprehensive IP intelligence to identify threats, detect anonymization, and streamline abuse reporting.
The Challenge
Security teams face an overwhelming volume of suspicious IPs across firewalls, WAFs, and application logs. Determining whether an IP belongs to a legitimate VPN user, a known botnet, or a Tor exit node requires querying multiple threat feeds and WHOIS databases manually. Reporting abuse to the correct ISP is equally fragmented, with no single source for abuse contact information.
The Solution
Use EdgeDNS IP intelligence APIs to build automated threat enrichment pipelines. Check IP reputation against blacklists and threat feeds, detect VPN/proxy/Tor/datacenter usage, look up WHOIS registration and abuse contacts, and correlate with geolocation and reverse DNS for complete context.
Endpoints Used
Combine these EdgeDNS endpoints to build this solution.
/v1/ip/reputationTry in PlaygroundIP Reputation: Check IP against blacklists, spam databases, and threat feeds
/v1/ip/privacyTry in PlaygroundIP Privacy Detection: Detect VPN, proxy, Tor exit nodes, and datacenter IPs
/v1/ip/whoisTry in PlaygroundIP WHOIS: Get WHOIS registration data, contacts (including abuse), and network ownership for any IP
/v1/ip/geolocationTry in PlaygroundIP Geolocation: Get country, city, ISP, and ASN for geographic context
/v1/ip/reverseTry in PlaygroundReverse DNS: Resolve IP to hostname via PTR records for identification
Results You Can Achieve
Automate threat triage
Instantly classify IPs as malicious, suspicious, or benign based on reputation scores
Detect anonymized attackers
Identify VPN, proxy, and Tor usage to flag evasion attempts in real-time
Streamline abuse reporting
Use IP WHOIS contacts to identify the responsible network operator and file abuse reports
Code Example
Comprehensive IP threat assessment
async function assessIPThreat(ipAddress) {
const headers = { 'Authorization': 'Bearer YOUR_API_KEY' };
const [reputation, privacy, whois, geo, reverse] = await Promise.all([
fetch(`https://api.edgedns.dev/v1/ip/reputation?ip=${ipAddress}`, { headers }),
fetch(`https://api.edgedns.dev/v1/ip/privacy?ip=${ipAddress}`, { headers }),
fetch(`https://api.edgedns.dev/v1/ip/whois?ip=${ipAddress}`, { headers }),
fetch(`https://api.edgedns.dev/v1/ip/geolocation?ip=${ipAddress}`, { headers }),
fetch(`https://api.edgedns.dev/v1/ip/reverse?ip=${ipAddress}`, { headers }),
].map(p => p.then(r => r.json())));
const abuseContact = whois.data.contacts?.find(c => c.role === 'abuse');
const threatLevel =
reputation.data.is_malicious ? 'critical' :
privacy.data.is_tor ? 'high' :
privacy.data.is_vpn || privacy.data.is_proxy ? 'medium' : 'low';
return {
ip: ipAddress,
threatLevel,
reputation: {
isMalicious: reputation.data.is_malicious,
detections: reputation.data.detections,

},
privacy: {
isVPN: privacy.data.is_vpn,
isProxy: privacy.data.is_proxy,
isTor: privacy.data.is_tor,
isDatacenter: privacy.data.is_datacenter
},
location: geo.data.country + ', ' + geo.data.city,
hostname: reverse.data.hostname,
abuseContact: abuseContact?.email ?? null,
action: threatLevel === 'critical' ? 'BLOCK' : threatLevel === 'high' ? 'CHALLENGE' : 'ALLOW'
};
