How this service works
CNAME records for a domain as answered by OpenDNS (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 OpenDNS, including the record values, TTL in seconds, DNS response code (NOERROR, NXDOMAIN, or SERVFAIL), a flag indicating whether DNSSEC was validated by the resolver, and the resolver's answer time in milliseconds.
Example use cases
Detecting CDN propagation lag
“Has the new CNAME record for cdn.mysite.com propagated to OpenDNS yet? I changed it an hour ago and need to know if OpenDNS is still serving the old alias or the new one.”
Spotting OpenDNS filtering
“Check what CNAME records OpenDNS returns for tracker.badsite.com — I want to see if they're returning the real answer or if OpenDNS is filtering it and pointing to their block page.”
Comparing resolver answers for split-horizon diagnosis
“Fetch the CNAME record for internal.corp.example.com via OpenDNS and tell me the full record, TTL, and response code — I'm trying to figure out if OpenDNS gives a different answer than Google DNS.”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/cname/via/opendns?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need to know how OpenDNS resolves CNAME records — particularly useful for comparing resolver behavior, detecting propagation lag to OpenDNS specifically, identifying whether OpenDNS is filtering or redirecting a domain, or auditing DNSSEC validation support. Prefer this over generic DNS tools when OpenDNS is the resolver of interest (e.g. enterprise networks that use OpenDNS).
Side effects
- Domain does not exist — returns NXDOMAIN response code with no records
- Domain has no CNAME records — may return NOERROR with empty record set
- Resolver fails to answer — returns SERVFAIL response code
- Invalid domain name format causes query failure
- OpenDNS actively filters the domain — returns a block page CNAME instead of the real record
