How this service works
CNAME records for a domain as answered by NextDNS (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 CNAME records for the queried domain as answered by NextDNS, including the canonical name(s), TTL, DNS response code (NOERROR, NXDOMAIN, or SERVFAIL), whether DNSSEC was validated, and the resolver's answer time in milliseconds.
Example use cases
Compare CNAME propagation across resolvers
“Check what CNAME record NextDNS returns for shop.mystore.com — I want to see if it matches what other resolvers are reporting and how long the TTL is.”
Detect NextDNS filtering of a domain
“Is NextDNS blocking or filtering CNAME lookups for malware-test.example.org? Tell me if the response is NOERROR, NXDOMAIN, or SERVFAIL.”
Verify DNSSEC validation on CNAME record
“Look up the CNAME record for mail.company.com through NextDNS and tell me whether DNSSEC was validated and how fast the resolver answered.”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/cname/via/nextdns?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need to see how NextDNS resolves CNAME records — particularly for comparing resolver behavior, detecting filtering or split-horizon DNS, checking DNS propagation as seen by NextDNS, or verifying DNSSEC validation. Use over generic DNS tools when NextDNS-specific behavior (privacy filtering, security policies) is the variable under investigation.
Side effects
- Domain does not exist — response code NXDOMAIN returned
- NextDNS filters the domain — may return NXDOMAIN or blocked response instead of actual record
- No CNAME record exists for domain — empty records with NOERROR
- Resolver error — SERVFAIL response code
- Invalid or malformed domain name input — request rejected
- Network timeout reaching NextDNS DoH endpoint
