How this service works
CNAME records for a domain as answered by AdGuard DNS (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 record set for the queried domain as answered by AdGuard DNS over HTTPS, including: the actual CNAME target records, TTL value, DNS response code (NOERROR, NXDOMAIN, or SERVFAIL), whether the resolver performed DNSSEC validation, and the resolver's answer latency in milliseconds.
Example use cases
Diagnosing CNAME filtering by AdGuard
“Check if AdGuard DNS is filtering or blocking the CNAME for tracking.example.com — tell me the response code it returns and whether it differs from what a normal resolver would give.”
Verifying CNAME propagation after DNS update
“I just updated the CNAME record for shop.mybrand.com — can you query AdGuard DNS right now and tell me if they're already returning the new target, along with the TTL and answer time?”
Comparing resolver answers for split-horizon detection
“Look up the CNAME record for internal.acme.com via AdGuard DNS and tell me the response code and record value — I want to see if AdGuard gives a different answer than other resolvers for the same domain.”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/cname/via/adguard?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need to know how AdGuard DNS resolves a domain's CNAME records — particularly useful for detecting AdGuard's ad/tracker filtering behavior, checking DNSSEC validation status, comparing resolver-specific propagation lag, or diagnosing split-horizon DNS scenarios where AdGuard may return different answers than other public resolvers like Google or Cloudflare.
Side effects
- Domain does not exist — AdGuard returns NXDOMAIN with no CNAME records
- Domain has no CNAME record — response may be NOERROR with empty answer section
- AdGuard DNS is temporarily unavailable — SERVFAIL response code returned
- Network timeout reaching AdGuard DoH endpoint — resolver latency field may be absent
- Invalid or malformed domain input — request may fail with a client-side error
- AdGuard actively filters the domain — returns NXDOMAIN even if domain exists globally
