How this service works
Change watch for ip whois rdap: runs the check and compares it with the result from your previous call for the same ip (kept 90 days), returning the current answer, changed true/false, exactly which fields changed with before/after values, and when it was last seen. Call it on a schedule to be told when ip whois via rdap changes. $0.01 per check.
Output
Returns the current RDAP WHOIS data for the IP, a boolean 'changed' flag indicating whether anything has changed since the previous call, a list of exactly which fields changed with before and after values, and a timestamp of when the IP was last seen. Previous results are retained for 90 days.
Example use cases
Monitor IP ownership changes for security
“Set up a recurring check on the RDAP whois record for 192.0.2.45 and alert me if the owner, org, or contact info changes at all.”
Track IP block reassignment over time
“Has the WHOIS RDAP registration for 203.0.113.10 changed since last week? Show me exactly which fields are different and what the before and after values are.”
Detect IP hijacking or prefix reassignment
“I need to watch 198.51.100.0 for any RDAP whois changes — run the check now and tell me if anything is different from the last result you have stored.”
Technical details
Endpoint
GEThttps://intel.rallylive.ca/watch/ip/rdapWhen to prefer
Choose this endpoint when you need to detect changes in IP WHOIS/RDAP registration data over time rather than just a one-time lookup. Ideal for scheduled monitoring pipelines, security alerting, or tracking IP ownership and assignment changes. Prefer this over a plain RDAP lookup when you need diff tracking with before/after field values and historical comparison.
Side effects
- IP address not provided or malformed — endpoint may return an error or empty result
- No prior result stored (first-time call) — returns current data but changed flag may be false or undefined
- IP not found in RDAP registries — may return empty or partial RDAP data
- Cached result expired beyond 90 days — previous baseline is lost, treated as first call
- Rate limiting or payment failure — call blocked if payment not processed correctly
