How this service works
Change watch for ip to asn: 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 to asn lookup changes. $0.01 per check.
Output
Returns the current IP-to-ASN mapping, a boolean 'changed' flag indicating whether the result differs from the previous call for the same IP (stored up to 90 days), a list of exactly which fields changed with before and after values, and a timestamp of when the IP was last seen.
Example use cases
ISP migration detection for a monitored host
“Check the ASN for 203.0.113.42 and tell me if it's changed since last time — I want to know if this server has switched ISPs or moved to a different network.”
Threat intel routing change alert
“I'm tracking a known malicious IP at 185.220.101.5. Has its ASN changed recently? Tell me what changed, what it was before, and when it was last seen.”
Scheduled network infrastructure monitoring
“Run the IP-to-ASN watch check on 1.1.1.1 and report back whether the ASN mapping has changed, and if so, what fields flipped and what the old versus new values are.”
Technical details
Endpoint
GEThttps://intel.rallylive.ca/watch/ip/asnWhen to prefer
Use this endpoint when you need to detect changes in an IP's ASN mapping over time rather than just performing a one-time lookup. It is ideal for scheduled monitoring workflows where you want to be notified of BGP routing changes, ISP migrations, or network reassignments without maintaining your own state — the service stores the last result for 90 days and handles the diff computation for you.
Side effects
- IP address not provided or malformed — query parameter missing or invalid format
- No previous result exists for the IP (first call returns current data with changed=false or null diff)
- Stored result has expired beyond the 90-day window — comparison unavailable
- Payment failure via x402 — endpoint returns 402 if USDC payment is not included
- Network or upstream ASN data source unavailable — may return error or stale data
