How this service works
Change watch for reverse dns via cloudflare: 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 PTR record result, a boolean 'changed' flag, a list of fields that changed with their before and after values, and the timestamp of when the record was last seen. Previous result is retained for 90 days.
Example use cases
Detect IP reassignment via PTR change
“Watch the reverse DNS for 203.0.113.45 via Cloudflare and tell me if the PTR record has changed since the last time we checked — show me the before and after values.”
Monitor CDN or hosting provider change
“I want to track whether the reverse DNS for 104.21.10.30 changes over time using Cloudflare — flag it immediately if the PTR record shifts to a different hostname.”
Automated alert for suspicious IP reclassification
“Set up a watch on the reverse DNS for 192.0.2.100 through Cloudflare so I get alerted with field-level diffs if its PTR record ever changes.”
Technical details
Endpoint
GEThttps://ip.intel.rallylive.ca/watch/ip/ptr/via/cloudflare?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to detect changes in reverse DNS (PTR) specifically resolved via Cloudflare DNS, with automatic diffing against the previous known result. Ideal for scheduled polling workflows where you want to be alerted to hostname changes for a given IP without managing your own state — the service stores the prior result for up to 90 days.
Side effects
- IP address not provided or malformed — returns error
- No previous call exists for this IP, so 'changed' will be false with no diff on first call
- Cloudflare DNS lookup failure — no PTR result returned
- 90-day history expired — treated as first call with no comparison data
- Rate limit or payment failure — call rejected
