How this service works
NS records for a domain as answered by Cloudflare 1.1.1.1 (DNS over HTTPS): the records, TTL, response code (NOERROR/NXDOMAIN/SERVFAIL), whether the resolver validated DNSSEC, and the resolver's answer time. Compare resolvers to spot propagation lag, filtering or split-horizon answers. $0.01 per lookup.
Output
Returns the NS records (nameserver hostnames) for the queried domain as resolved by Cloudflare 1.1.1.1 via DNS over HTTPS, along with the TTL of the records, the DNS response code (NOERROR, NXDOMAIN, or SERVFAIL), a boolean indicating whether Cloudflare validated DNSSEC for the response, and the resolver's answer latency in milliseconds.
Example use cases
Verify nameserver propagation to Cloudflare
“Has the nameserver change for mybrand.io propagated to Cloudflare 1.1.1.1 yet? I just updated the NS records and want to see if Cloudflare is returning the new ones.”
Detect split-horizon nameserver answers
“I suspect our DNS provider is giving different NS records to Cloudflare than to other resolvers — can you look up the NS records for corp.internal.example.com via Cloudflare and tell me what they return, including the response code and DNSSEC flag?”
Audit DNSSEC validation on NS records
“Check the NS records for paymentgateway.io using Cloudflare's DNS and tell me whether DNSSEC is being validated — I need to confirm the delegation is secure.”

Endpoint
GEThttps://dns.intel.rallylive.ca/dns/ns/via/cloudflare?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need NS record results as seen by Cloudflare 1.1.1.1, for example to check nameserver propagation to Cloudflare's global resolver network, compare answers between resolvers to detect filtering or split-horizon configurations, or verify DNSSEC validation status of nameserver delegation. Choose this over generic DNS tools when Cloudflare's perspective specifically matters.
Side effects
- Domain does not exist — returns NXDOMAIN response code with no records
- Domain has no NS records — returns NOERROR with empty answer section
- DNS resolution fails at Cloudflare — returns SERVFAIL response code
- DNSSEC validation failure — DNSSEC flag false despite signed zone
- Network timeout reaching Cloudflare DoH endpoint — request error
- Invalid or malformed domain name input — request rejected
