How this service works
Change watch for dns a via google: 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 resolved by Google DNS, a boolean 'changed' flag indicating whether the result differs from the previous call (stored up to 90 days), a list of fields that changed with their before and after values, and the timestamp of when the record was last seen.
Example use cases
Website IP migration detection
“Watch the DNS A record for mycompany.com via Google DNS and tell me if the IP has changed since the last check — I want to know the moment we get migrated to the new server.”
CDN failover alerting
“Monitor the A record for cdn.myapp.io using Google DNS and alert me if it changes — I need to catch any unexpected CDN failovers right away.”
Competitor infrastructure tracking
“Check whether the DNS A record for competitor.com has changed since the last time you looked, using Google DNS, and show me the before and after values if it has.”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/watch/dns/a/via/google?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to detect changes in a domain's A record specifically as resolved by Google DNS, and you want a stateful diff (before/after) rather than just the current value. Ideal for scheduling periodic checks and triggering alerts on IP changes. Prefer this over plain DNS lookup endpoints when change detection and history (90-day retention) are required.
Side effects
- Domain not found or NXDOMAIN — returns empty record set
- No previous result stored (first call) — changed may be false or undefined with no diff
- Google DNS resolution failure — upstream timeout or error returned
- Invalid domain name input — request rejected
- Rate limiting or payment failure — endpoint returns error
