How this service works
Bulk ip listed on sorbs dul: up to 20 ips in one call, processed concurrently, results in input order with a per-item error field and a failure count. Same answer per item as the single endpoint. Batch enrichment for agents that hold a list. $0.10 per batch.
Output
An ordered array of per-IP results matching the input order, each indicating whether that IP is listed on SORBS DUL (the dial-up/dynamic user list), along with a per-item error field if the check failed for that IP, and an overall failure count for the batch.
Example use cases
Email sender reputation screening
“I have a list of 18 IP addresses from inbound email senders — can you check all of them against the SORBS DUL blacklist at once and tell me which ones are flagged as dynamic or dial-up IPs?”
Pre-send deliverability audit
“Before we send our next campaign, check these 20 outbound mail server IPs against the SORBS DUL list in one go and give me a summary of which are blocked and if any lookups failed.”
Threat intelligence enrichment pipeline
“I'm building a report on suspicious IPs collected from our firewall logs — run all 12 of these IPs through the SORBS DUL blacklist check simultaneously and return the results in the same order I gave them.”
Technical details
Endpoint
GEThttps://ip.intel.rallylive.ca/bulk/ip/blacklist/sorbs-dul?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to check multiple IPs (up to 20) against the SORBS DUL blacklist in a single API call rather than making individual requests. It is more cost-efficient and faster for batch workloads compared to calling the single-IP endpoint repeatedly. Prefer it when processing email sender lists, firewall log IPs, or any scenario where you hold a list of IPs to screen for dynamic/dial-up status simultaneously.
Side effects
- Individual IP check fails (network or DNS timeout) — reported in per-item error field, failure count incremented
- Invalid IP address format in input — per-item error returned
- Batch exceeds 20 IPs — request rejected or truncated
- Service unavailability — entire batch call returns error
