Output
Returns a JSON object with the queried IP, an overall listed boolean, a list of checked DNSBL zones each with their name, listed status, description, and DNS return code, plus a count of how many lists the IP appeared on and the total number of lists checked.
Example use cases
Email server IP reputation check
“Before I send my email campaign, can you check if my mail server IP 203.0.113.42 is blacklisted on any DNSBL like Spamhaus, SpamCop, or SORBS?”
Investigating suspicious inbound traffic
“I'm seeing a lot of suspicious traffic from IP 91.108.4.15 — can you run it through the DNSBL blacklists and tell me how many lists it shows up on?”
Onboarding user IP trust verification
“We just got a new user signing up from IP 198.51.100.77 — can you check if that IP is on any spam or abuse blacklists before we approve their account?”
Technical details
Endpoint
POSThttps://api.getapi.nl/api/v1/validate/dnsblWhen to prefer
Use this endpoint when you need to check an IP's spam or abuse reputation across multiple established DNSBL zones (Spamhaus, SpamCop, SORBS, Barracuda, PSBL) in a single call. Prefer this over manual DNS lookups when you need consolidated multi-blacklist results with descriptions and return codes. Ideal for email deliverability verification, fraud detection pipelines, and network security triage.
Side effects
- Invalid or malformed IP address returns an error
- Private or reserved IP ranges may return unexpected results
- A DNSBL zone being temporarily unavailable may affect result completeness
- Network timeouts may cause incomplete blacklist checks
