How this service works
Change watch for dns ns via nextdns: 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 NS records as resolved by NextDNS, a boolean 'changed' flag indicating whether the records differ from the previous call, a list of fields that changed with before/after values, and the timestamp of when the result was last seen. Previous results are retained for 90 days for comparison.
Example use cases
Detect domain hijacking via NS change
“Watch the NS records for mybrand.com using NextDNS and alert me immediately if the nameservers change — I'm worried about unauthorized domain transfers.”
Track DNS provider migration
“I'm migrating clientsite.io to a new DNS provider next week. Can you monitor the NS records via NextDNS and confirm when the nameserver change has propagated?”
Audit nameserver stability over time
“Set up a recurring check on the nameservers for acmecorp.com via NextDNS and tell me if anything changes from what they are right now — I need to track this for our security audit.”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/watch/dns/ns/via/nextdns?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to detect changes to NS (nameserver) records specifically as seen through NextDNS's DNS-over-HTTPS resolver — ideal for security monitoring, detecting domain hijacking, validating DNS migrations, or automating alerts when a domain switches DNS providers. Prefer this over a plain NS lookup when you need stateful change detection rather than just the current value.
Side effects
- Domain not found or invalid — NXDOMAIN response with no records
- NextDNS resolver unreachable — upstream DNS error returned
- No previous result stored (first call) — changed flag may be null or false with no diff available
- Domain query times out — timeout or error response
- Malformed domain input — validation error
