How this service works
SOA 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 SOA record data (primary nameserver, responsible mailbox, serial, refresh, retry, expire, minimum TTL), the record TTL, the DNS response code (NOERROR, NXDOMAIN, or SERVFAIL), a boolean indicating whether Cloudflare validated DNSSEC, and the resolver's answer latency in milliseconds.
Example use cases
DNS propagation check after zone change
“I just updated the SOA serial number for mycompany.com — can you query Cloudflare 1.1.1.1 for its SOA record and tell me the current serial, TTL, and response code so I can confirm the change is propagating?”
Detecting split-horizon or resolver filtering
“I suspect Cloudflare is returning a different SOA for internal.acmecorp.com than our corporate resolver — can you fetch the SOA record via Cloudflare DoH and show me the records and response code so I can compare?”
DNSSEC validation audit
“Can you check whether Cloudflare 1.1.1.1 is successfully validating DNSSEC on the SOA record for dnssec-test.example.net and report the validation status and answer time?”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/soa/via/cloudflare?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need SOA record data as seen by Cloudflare 1.1.1.1, particularly for cross-resolver propagation comparisons, DNSSEC audit workflows, or diagnosing split-horizon DNS. Prefer it over generic DNS tools when you need structured output including DNSSEC validation status and precise answer time from Cloudflare's public resolver.
Side effects
- NXDOMAIN returned if the domain does not exist or has no SOA record
- SERVFAIL if the upstream resolver encountered an error or DNSSEC validation failed
- Network timeout if Cloudflare DoH is unreachable
- Empty records array if the domain exists but has no SOA entry
- Payment failure if USDC balance is insufficient for the $0.01 fee
