How this service works
SVCB 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 SVCB records for the queried domain as answered by OpenDNS via DNS over HTTPS, including the record data, TTL, DNS response code (NOERROR, NXDOMAIN, or SERVFAIL), a flag indicating whether the resolver performed DNSSEC validation, and the resolver's answer time in milliseconds.
Example use cases
Detect OpenDNS SVCB filtering
“Check if OpenDNS is filtering or altering SVCB records for myapp.io — show me the records, response code, and whether DNSSEC was validated.”
Compare resolver propagation lag
“I just updated the SVCB records for api.mybusiness.com — can you check what OpenDNS is currently returning so I can compare it against other resolvers and see if changes have propagated?”
Debug SVCB split-horizon answers
“Query the SVCB records for secure.mybank.com via OpenDNS and tell me the TTL and response code — I'm trying to figure out if OpenDNS is returning different answers than other resolvers.”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/svcb/via/opendns?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need to know what OpenDNS returns for SVCB records — for instance to detect OpenDNS-specific filtering, check propagation on OpenDNS's resolver network, or compare OpenDNS answers against other resolvers like Cloudflare or Google. Choose sibling endpoints for other record types (A, AAAA, TXT, CNAME) or other resolvers (DNSPod, NextDNS, CleanBrowsing).
Side effects
- Domain does not exist — returns NXDOMAIN response code with empty records
- OpenDNS resolver error — returns SERVFAIL response code
- No SVCB records configured for the domain — returns NOERROR with empty record set
- Timeout or connectivity issue reaching OpenDNS DoH endpoint
- Malformed domain name input causing query failure
