How this service works
Change watch for reverse dns via dnspod: 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 answer from DNSPod, a boolean indicating whether it changed since the last call for that IP, the specific fields that changed with their before and after values, and the timestamp of when it was last seen. Previous results are retained for 90 days.
Example use cases
Server infrastructure PTR drift detection
“Watch the reverse DNS record for 198.51.100.10 via DNSPod and tell me if it's changed since the last check — I want to know the before and after values if it has.”
Security alerting on IP hostname changes
“Set up monitoring on the reverse DNS for 192.0.2.55 through DNSPod so I get alerted the moment its PTR record changes — it could indicate something suspicious.”
CDN or hosting migration verification
“Check if the reverse DNS for 104.21.3.17 has changed via DNSPod since I last looked — we recently migrated hosting and I want to confirm the PTR record updated correctly.”
Technical details
Endpoint
GEThttps://ip.intel.rallylive.ca/watch/ip/ptr/via/dnspod?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically want to use DNSPod as the resolving nameserver for reverse DNS change detection, allowing cross-resolver comparison or when DNSPod's view of DNS is particularly relevant. Prefer it over the CleanBrowsing or AliDNS variants when you need DNSPod's resolver perspective for Chinese or Asia-Pacific network infrastructure. Use it over a plain PTR lookup when you need change detection with before/after diffing rather than just the current value.
Side effects
- IP address not provided or invalid format — returns error
- No previous check stored for this IP (first call) — change flag may be false or indeterminate
- DNSPod resolver unavailable — lookup may fail or time out
- IP has no PTR record — returns empty/null answer
- Stored result expired (older than 90 days) — treated as no prior result
