How this service works
SRV 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 SRV records for the queried domain (including priority, weight, port, and target), the TTL, the DNS response code (NOERROR, NXDOMAIN, or SERVFAIL), a flag indicating whether the NextDNS resolver validated DNSSEC, and the resolver's answer time in milliseconds.
Example use cases
Troubleshoot SIP service discovery
“I need to check the SRV records for voip-provider.com via NextDNS — can you pull them and tell me if DNSSEC validated and what the TTL is? I want to see if NextDNS is returning the right records for SIP routing.”
Compare resolver propagation for SRV
“I'm debugging a DNS propagation issue for myapp.io. Can you query the SRV records through NextDNS and give me the response code and answer time so I can compare it against other resolvers?”
Detect NextDNS filtering on SRV records
“Can you check if NextDNS is filtering or blocking SRV records for gaming-service.net? I want to see the full SRV response, response code, and whether it's a NOERROR or NXDOMAIN.”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/srv/via/nextdns?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically want to see how NextDNS (with its privacy and security filtering features) resolves SRV records, particularly to detect filtering, compare propagation lag against other resolvers, or verify DNSSEC validation status via a privacy-focused DoH resolver. Use it when NextDNS is the resolver of interest rather than a generic or authoritative lookup.
Side effects
- Domain does not exist — returns NXDOMAIN response code with no records
- Resolver fails to answer — returns SERVFAIL response code
- Domain has no SRV records — returns NOERROR with empty record set
- Invalid domain name format — request may be rejected or return an error
- NextDNS may filter or block certain queries based on its security policies, returning different results than authoritative resolvers
