How this service works
SVCB records for a domain as answered by Cloudflare 1.1.1.1 (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 resource records for the queried domain, their TTL, the DNS response code (NOERROR, NXDOMAIN, or SERVFAIL), a boolean indicating whether Cloudflare validated DNSSEC for the response, and the resolver's answer time in milliseconds.
Example use cases
Debugging SVCB propagation via Cloudflare
“Check what SVCB records Cloudflare 1.1.1.1 is returning for mybrand.com — I want to see the TTL, response code, and whether DNSSEC validated, so I can tell if my recent DNS changes have propagated there yet.”
Detecting Cloudflare DNS filtering
“Can you query the SVCB records for myservice.io via Cloudflare DoH and let me know if it comes back NOERROR or something else? I'm trying to figure out if Cloudflare is filtering the response.”
Comparing resolver SVCB answers
“Pull the SVCB record for api.example.net from Cloudflare 1.1.1.1 — I need the answer, TTL, and response time so I can compare it against what NextDNS and Mullvad are returning to spot any split-horizon differences.”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/svcb/via/cloudflare?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need SVCB record data as seen by Cloudflare 1.1.1.1, particularly when comparing resolver behavior, debugging propagation lag, or checking whether Cloudflare is filtering or returning split-horizon answers. Prefer this over generic DNS tools when DNSSEC validation status and resolver answer timing are important to your analysis.
Side effects
- Domain does not exist — returns NXDOMAIN response code with empty records
- Resolver upstream failure — returns SERVFAIL response code
- No SVCB records exist for the domain — returns NOERROR with empty answer section
- Invalid or malformed domain name input — may return error or SERVFAIL
- Cloudflare DoH endpoint temporarily unreachable — request may time out or return an error
