How this service works
CAA 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 CAA DNS records for the queried domain as answered by NextDNS, including the record values, TTL, DNS response code (NOERROR, NXDOMAIN, or SERVFAIL), whether DNSSEC was validated, and the resolver's answer latency.
Example use cases
Verify CAA records before SSL issuance
“Check what CAA records NextDNS returns for mybusiness.com — I need to make sure only Let's Encrypt is authorized to issue certificates for it.”
Compare resolver propagation for CAA
“I just updated the CAA records for clientsite.io — can you check what NextDNS is returning right now so I can see if the changes have propagated?”
Audit DNSSEC validation on CAA records
“Look up the CAA records for securecorp.net via NextDNS and tell me whether DNSSEC validation passed and how fast the resolver answered.”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/caa/via/nextdns?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need to see how NextDNS resolves CAA records for a domain — particularly useful for comparing resolver behavior, detecting propagation lag, identifying filtering differences, or confirming DNSSEC validation status from NextDNS's perspective. Use alongside sibling resolvers (e.g., AdGuard, Cloudflare) to spot split-horizon or resolver-specific discrepancies.
Side effects
- NXDOMAIN returned if the domain does not exist
- SERVFAIL if the upstream resolver or domain is unreachable
- Empty records array if no CAA records are published for the domain
- DNSSEC validation failure indicated in response if domain has broken DNSSEC chain
- Network timeout if NextDNS is temporarily unavailable
