How this service works
DS 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 DS records for the queried domain as resolved by Mullvad DNS over HTTPS, including the record values, TTL, DNS response code (NOERROR, NXDOMAIN, or SERVFAIL), a flag indicating whether the resolver performed DNSSEC validation, and the resolver's answer latency in milliseconds.
Example use cases
Verify DNSSEC chain of trust
“Check the DS records for mycompany.com through Mullvad DNS and confirm whether the DNSSEC chain of trust is being validated correctly — include the response code and answer time.”
Compare resolver propagation for DS records
“I just updated the DS records for clientdomain.net — can you query it via Mullvad DNS over HTTPS to see if the new records have propagated yet, and show me the TTL and response code?”
Detect split-horizon or filtering on DS records
“Query the DS records for securedomain.org using Mullvad DoH and tell me what records come back, what the response code is, and whether DNSSEC was validated — I want to see if Mullvad is giving a different answer than other resolvers.”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/ds/via/mullvad?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need DS records as seen by the Mullvad DNS over HTTPS resolver — ideal for comparing DNSSEC delegation signer records across resolvers, auditing DNSSEC chain-of-trust integrity, detecting propagation lag after DS record updates, or identifying split-horizon/filtering behavior unique to Mullvad's resolver. Choose this over generic DNS lookups when resolver identity and DNSSEC validation status matter.
Side effects
- Domain does not exist — returns NXDOMAIN response code with empty records
- Mullvad resolver is temporarily unreachable — may return SERVFAIL or timeout
- Domain has no DS records — returns NOERROR with empty answer section
- Malformed domain name input — may result in resolver error or no response
- DNSSEC validation failure at resolver — SERVFAIL with DO bit set
