How this service works
TXT records for a domain as answered by NextDNS (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 NextDNS, including: the text record values, TTL in seconds, DNS response code (NOERROR, NXDOMAIN, or SERVFAIL), whether NextDNS validated DNSSEC for the response, and the resolver's answer time in milliseconds.
Example use cases
Verify SPF record via NextDNS
“Look up the TXT records for mydomain.com through NextDNS and tell me if there's a valid SPF record present, what the TTL is, and whether DNSSEC was validated.”
Detect NextDNS filtering on TXT records
“Check if NextDNS is filtering or blocking TXT record responses for acme-corp.com — I want to see the response code, the actual records returned, and how long the resolver took to answer.”
Compare TXT record propagation across resolvers
“I need to compare TXT records for newlydelegated.io across different resolvers — start by fetching what NextDNS returns, including the TTL and response code, so I can see if it's propagated there yet.”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/txt/via/nextdns?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically want to see how NextDNS resolves TXT records — useful for detecting NextDNS-specific filtering, privacy policies, or split-horizon behavior. Prefer this over generic DNS lookups when comparing resolver behavior across providers, checking DNSSEC validation by NextDNS specifically, or diagnosing propagation discrepancies that are resolver-dependent.
Side effects
- Domain does not exist: returns NXDOMAIN response code with empty records
- Resolver error or upstream failure: returns SERVFAIL response code
- Domain has no TXT records: returns NOERROR with empty record set
- Network timeout to NextDNS: may result in request failure or latency spike
- Invalid domain name input: may return an error or SERVFAIL
