How this service works
TXT 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 TXT record set for the queried domain as answered by Mullvad's DNS-over-HTTPS resolver, including: the raw TXT record strings, their TTL (time-to-live in seconds), the DNS response code (NOERROR, NXDOMAIN, or SERVFAIL), a boolean indicating whether Mullvad validated DNSSEC for this response, and the resolver's answer latency in milliseconds.
Example use cases
SPF record propagation check
“Check the TXT records for acme.com through Mullvad's DNS resolver — I want to see if the new SPF record I published has propagated there yet, including the TTL and response code.”
DMARC policy visibility audit
“Query the TXT records for _dmarc.mybrand.io via Mullvad DNS so I can confirm the DMARC policy is visible from that resolver and see whether DNSSEC is being validated.”
Split-horizon DNS detection
“Look up the TXT records for internal.company.com using Mullvad DoH and tell me the response code and records — I'm trying to detect if Mullvad gets a different answer than our corporate resolver.”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/txt/via/mullvad?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need to see how Mullvad's privacy-focused DNS-over-HTTPS resolver answers TXT record queries — particularly when comparing resolver responses across providers to detect propagation differences, filtering, or split-horizon DNS configurations. Ideal for security audits requiring a privacy-respecting resolver perspective, or when verifying SPF/DMARC/domain-verification TXT records from a non-ISP, non-Google vantage point.
Side effects
- Domain does not exist — returns NXDOMAIN response code with no records
- Resolver fails to answer — returns SERVFAIL response code
- No TXT records exist for the domain — NOERROR with empty record set
- DNSSEC validation failure — resolver may not validate and flag accordingly
- Network timeout reaching Mullvad DoH endpoint — may return error or high latency
- Malformed domain input — request may be rejected or return unexpected response
