How this service works
Change watch for dns a via mullvad: runs the check, compares it with the result from your previous call for the same domain (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 DNS A record answer for the domain as seen through Mullvad's resolver, a boolean 'changed' flag comparing to the last stored result (retained 90 days), a list of fields that changed with before/after values, and a timestamp of when the record was last seen in that state.
Example use cases
Detect unauthorized IP hijacking
“Keep an eye on the DNS A record for mybusiness.com through Mullvad — alert me the moment the IP address changes compared to what it was last time you checked.”
Validate CDN migration rollout
“Check the DNS A record for api.myapp.io via Mullvad and compare it to the previous reading — I want to confirm the IP has flipped to our new CDN address and see the before/after.”
Scheduled ISP-agnostic DNS monitoring
“Poll the DNS A record for competitor.com through Mullvad every hour and tell me whenever you see a change, including which fields changed and when it was last seen stable.”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/watch/dns/a/via/mullvad?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to detect DNS A record changes specifically as observed through Mullvad's privacy-focused resolver, which may differ from mainstream resolvers due to filtering or geolocation. Ideal for scheduled monitoring workflows where you want diff-style change detection with before/after values rather than just a raw current lookup. Prefer over generic DNS lookup endpoints when change alerting and historical comparison matter.
Side effects
- Domain not found / NXDOMAIN — returns empty record set with no-change status
- No prior check stored — first call returns current state with changed=false and no diff
- Mullvad resolver unreachable — may return timeout or resolver error
- Invalid domain input — may return error or empty response
- 90-day history expiry — prior result purged, treated as first call
