How this service works
Look up passive DNS resolution history and reputation for a domain or IP address. For a domain: which IPs it has resolved to over time. For an IP: which hostnames have resolved to it, plus malicious/suspicious vendor detection counts. Call to pivot from an indicator to its infrastructure history during an investigation.
Output
Returns a JSON object with a boolean ok flag, the queried entity (IP or domain), query type, a numeric reputation score, a list of dated DNS resolutions with resolved IP addresses, plus counts of malicious and suspicious community votes.
Example use cases
Vetting an unknown inbound IP
“I'm seeing a lot of traffic from 93.184.216.34 in my logs — can you check its reputation and see if it's been flagged as malicious or suspicious?”
Screening a third-party domain before integration
“Before we connect our app to partner-api.xyz, can you look up its reputation score and check whether it's been marked as malicious or suspicious by the community?”
Investigating a phishing report
“A user reported a suspicious link pointing to verify-login-secure.net — can you pull up the IP intelligence on that domain including any malicious votes and recent DNS resolutions?”

Choose this endpoint when you need fast, pay-per-query IP and domain threat intelligence without a subscription — especially useful in agentic workflows that need to validate untrusted network entities on-demand, check reputation scores before making outbound connections, or triage security alerts involving unknown IPs or domains.
Side effects
- Invalid IP or domain format returns an error response
- Unknown or unindexed domain may return empty resolutions array
