How this service works
NAPTR records for a domain as answered by DNS.SB (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 NAPTR resource records for the queried domain as answered by DNS.SB over HTTPS, including the record data (order, preference, flags, service, regex, replacement), TTL, the DNS response code (NOERROR, NXDOMAIN, or SERVFAIL), whether DNSSEC was validated by the resolver, and the resolver's answer latency in milliseconds.
Example use cases
VoIP NAPTR routing verification
“Can you look up the NAPTR records for voip-provider.com using DNS.SB and tell me what service and regex values come back, plus whether DNSSEC was validated?”
Comparing resolver propagation lag
“I want to check if DNS.SB has picked up the new NAPTR records I just published for mycompany.com — can you query it and show me the TTL and response code?”
Detecting DNS filtering on NAPTR
“Is DNS.SB filtering or blocking NAPTR records for suspicious-site.net? Run a NAPTR lookup there and tell me the response code and whether any records came back.”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/naptr/via/dnssb?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need NAPTR records resolved via DNS.SB and want to compare its answers against other resolvers for propagation lag, DNSSEC validation coverage, or potential filtering differences. Prefer this over generic DNS lookups when NAPTR records (used for VoIP, ENUM, and URI routing) are the target and DNS.SB's resolution behavior is of interest.
Side effects
- Domain does not exist — returns NXDOMAIN response code with no records
- DNS.SB resolver fails — returns SERVFAIL response code
- Domain has no NAPTR records — returns NOERROR with empty answer section
- Network timeout reaching DNS.SB resolver — request may fail or return error
- Invalid domain input — may cause malformed query or error response
