How this service works
Change watch for dns cname 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 CNAME records as answered by Mullvad DNS, a boolean 'changed' flag indicating whether the answer differs from the previous call for the same domain, a diff of fields that changed with before/after values, and a timestamp of when the previous answer was last seen. Results from previous calls are retained for 90 days.
Example use cases
CDN cutover detection for a domain
“Watch the CNAME for assets.myapp.io via Mullvad and alert me if it stops pointing at our CDN provider — show me the before and after values.”
Detect unauthorized DNS hijacking
“Monitor the CNAME record for login.mycompany.com through Mullvad DNS and tell me the moment it changes to something unexpected, including what it changed from and to.”
Confirm domain migration completed
“Check whether the CNAME for www.newsite.com has updated to the new target yet via Mullvad — compare it to the last known value and tell me if it's changed.”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/watch/dns/cname/via/mullvad?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need change-detection semantics for DNS CNAME records specifically via Mullvad's resolver — ideal for scheduled polling workflows where you want automatic diffing against the last known state without maintaining your own state store. Prefer this over raw DNS CNAME lookups when you need before/after change visibility or want to detect DNS hijacking, CDN migrations, or routing changes from Mullvad's network vantage point.
Side effects
- Domain not provided or malformed — request fails with a validation error
- Domain has no CNAME record — returns empty record set with changed flag relative to prior state
- Mullvad DNS resolver is unreachable — may return a timeout or upstream error
- No prior result stored (first-ever call) — changed flag is false or null with no diff available
- Domain cached result expired past 90 days — treated as a fresh first call with no diff
