How this service works
SOA records for a domain as answered by Mullvad DNS (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 (MNAME, RNAME, serial, refresh, retry, expire, minimum TTL), the TTL of the response, the DNS response code (NOERROR, NXDOMAIN, or SERVFAIL), a boolean indicating whether the Mullvad resolver validated DNSSEC for this response, and the resolver's answer time in milliseconds.
Example use cases
DNS propagation lag detection
“Check the SOA record for newdomain.io through Mullvad DNS — I want to know the serial number, TTL, and response code so I can compare it against other resolvers and see if propagation has reached Mullvad yet.”
DNSSEC validation verification
“Query the SOA record for mybusiness.com via Mullvad's DoH resolver and tell me whether the response was DNSSEC-validated and what the response code was.”
Split-horizon or filtering check
“Pull the SOA record for corp-internal.net through Mullvad DNS and compare the answer — I'm trying to figure out whether Mullvad is filtering or returning a different answer than the authoritative nameserver.”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/soa/via/mullvad?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need to see how Mullvad's privacy-focused DNS resolver answers SOA queries — especially useful for comparing resolver behavior, detecting propagation lag, identifying filtering or split-horizon DNS setups, or verifying DNSSEC validation through a privacy-oriented resolver. Choose this over generic SOA lookups when resolver identity and DNSSEC status matter.
Side effects
- NXDOMAIN if the domain does not exist
- SERVFAIL if Mullvad cannot resolve or encounters an upstream error
- Missing or empty records if the domain has no SOA record
- Network timeout if the Mullvad DoH endpoint is unreachable
- Invalid domain input may result in an error or unexpected response code
