How this service works
Is this IPv4 address listed on nixspam (ix.dnsbl.manitu.net)? Performs the DNSBL query (reversed octets under ix.dnsbl.manitu.net, via Cloudflare DoH) and returns listed yes/no with the return codes and, where the list publishes one, the reason text. One list, one precise answer. $0.01 per lookup.
Output
Returns a yes/no listed status for the queried IPv4 address on ix.dnsbl.manitu.net, along with the DNSBL return codes and, where available, a human-readable reason text explaining why the IP is listed.
Example use cases
Pre-send email deliverability check
“Before we send the newsletter campaign from our mail server at 203.0.113.77, can you check if that IP is listed on NixSpam so we know if it might get blocked?”
Inbound mail server vetting
“We're getting suspicious emails from 198.51.100.22 — can you look it up on the NixSpam blacklist and tell me if it's listed and why?”
Automated IP reputation screening
“I need to know if 91.198.174.192 is on the NixSpam spam blacklist — please check ix.dnsbl.manitu.net and give me the return code and any reason provided.”
Technical details
Endpoint
GEThttps://ip.intel.rallylive.ca/ip/blacklist/nixspam?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a precise, single-list NixSpam DNSBL verdict for an IPv4 address, particularly for email deliverability checks, spam filtering pipelines, or IP reputation enrichment. Prefer it over multi-list DNSBL aggregators when you specifically need NixSpam (ix.dnsbl.manitu.net) data with return codes and reason text rather than a combined score across many lists.
Side effects
- Invalid or non-IPv4 address input — malformed query
- IP not found in DNSBL — returns listed: no with no reason text
- DNS resolution failure via Cloudflare DoH — may return an error or timeout
- Private/reserved IP addresses may not yield meaningful DNSBL results
- Payment failure — endpoint requires $0.01 USDC per call via x402
