How this service works
SOA records for a domain as answered by CleanBrowsing (security filter) (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 party, serial, refresh/retry/expire/minimum values), TTL, DNS response code (NOERROR, NXDOMAIN, or SERVFAIL), a boolean indicating whether CleanBrowsing validated DNSSEC, and the resolver's answer time in milliseconds.
Example use cases
Detect DNS filtering by security resolver
“Check what SOA record CleanBrowsing's DNS gives back for malware-domain.xyz — I want to see if it's being filtered or if the response code is something other than NOERROR.”
Compare propagation lag across resolvers
“I just updated the SOA record for mycompany.com — can you query it via CleanBrowsing and tell me the TTL and response time so I can compare against other resolvers to see if propagation has reached them?”
Verify DNSSEC validation on security resolver
“Does CleanBrowsing validate DNSSEC for cloudflare.com? Fetch the SOA record from CleanBrowsing and tell me if the DNSSEC flag is set and what the response code is.”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/soa/via/cleanbrowsing?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need to see how CleanBrowsing's security-filtering DNS resolver answers an SOA query — for example to detect whether a domain is being filtered/blocked, to compare resolver propagation speed against other resolvers, or to verify DNSSEC validation behavior on a security-focused resolver. Prefer sibling endpoints (e.g. dns-soa-via-dnspod) for the same SOA query answered by different resolvers.
Side effects
- NXDOMAIN returned if domain does not exist or is blocked by CleanBrowsing security filter
- SERVFAIL if the upstream resolver or domain's nameservers are unreachable
- Empty or filtered response if CleanBrowsing security policy blocks the domain
- Network timeout if CleanBrowsing DoH endpoint is temporarily unavailable
- Invalid domain input may result in an error response
