How this service works
TLSA records for a domain as answered by OpenDNS (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 TLSA DNS records for the queried domain as resolved by OpenDNS via DoH, including: the record data, TTL, response code (NOERROR, NXDOMAIN, or SERVFAIL), a boolean indicating whether the resolver performed DNSSEC validation, and the resolver's answer latency in milliseconds.
Example use cases
TLSA propagation check across resolvers
“Check the TLSA records for my domain mail.example.com via OpenDNS and tell me if they match what Cloudflare returns — I want to spot any propagation lag.”
DANE certificate pinning verification
“Look up the TLSA records for _443._tcp.example.com using OpenDNS and let me know if DNSSEC was validated and what the response code is — I need to confirm DANE is set up correctly.”
Split-horizon DNS detection
“Query TLSA records for _25._tcp.smtp.example.com through OpenDNS and tell me the full answer including TTL and answer time — I suspect this resolver is filtering or returning different results.”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/tlsa/via/opendns?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need TLSA record data specifically as seen by OpenDNS, to compare resolver behavior, detect propagation delays, or identify filtering/split-horizon differences versus other resolvers like Cloudflare or DNSPod. Ideal for DANE validation checks and DNSSEC compliance auditing from the OpenDNS perspective.
Side effects
- Domain does not exist — returns NXDOMAIN response code
- No TLSA records configured for the domain — empty records with NOERROR
- OpenDNS resolver is unreachable or times out — returns SERVFAIL
- Invalid domain format — may return an error or SERVFAIL
- DNSSEC validation failure — resolver may return SERVFAIL with AD flag unset
