How this service works
Change watch for ip listed on sorbs dul: runs the check, compares it with the result from your previous call for the same ip (kept 90 days) and returns the current answer, changed true/false, the fields that changed with before/after values, and when it was last seen. Schedule it to be alerted when this changes. $0.02 per check.
Output
Returns the current SORBS DUL blacklist status for the IP, a boolean indicating whether it changed since the last call (stored up to 90 days), a diff of fields that changed with before/after values, and the timestamp of when it was last seen.
Example use cases
Mail server IP reputation monitoring
“Watch the SORBS DUL blacklist status for our mail server at 198.51.100.22 and alert me if it gets listed or removed — I want to catch deliverability issues the moment they happen.”
ISP customer IP watchdog
“Set up a check on 203.0.113.99 against the SORBS DUL list and tell me whether it changed since the last check, including what exactly changed and when it was last seen.”
Security ops blacklist change tracking
“Has the SORBS DUL blacklist status changed for IP 192.0.2.10 compared to the last time it was checked? Show me what changed and the before and after values.”
Technical details
Endpoint
GEThttps://ip.intel.rallylive.ca/watch/ip/blacklist/sorbs-dul?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need ongoing change detection for SORBS DUL blacklist status rather than a one-time lookup. It is ideal for scheduled monitoring workflows where you want to be alerted only when the listing status actually changes, avoiding noise from repeated identical results. Prefer it over a plain blacklist check when you need historical comparison, before/after diffs, and a 'changed' signal to trigger downstream actions.
Side effects
- Invalid or malformed IP address returns an error
- IP not previously checked returns no diff (first-run baseline only)
- SORBS DUL service temporarily unavailable may cause lookup failure
- Previous result expired after 90 days resets the comparison baseline
- Rate limits or payment failures block the check
