How this service works

Query a domain's DNS record across 10 geographically distributed public resolvers simultaneously — returns what each resolver sees, whether results are consistent, propagation percentage, and a readiness score so agents can confirm DNS changes have fully propagated globally.

Output

Returns a per-resolver breakdown (name, IP, status, records returned, response time, majority match), a boolean consistency flag, the majority DNS value, a list of divergent resolvers, a propagation percentage (0–100), a letter grade (e.g. A), and a numeric readiness score.

Example use cases

Example prompt

“Has my DNS change fully propagated? Check the A record for mybrand.com across all public resolvers and tell me the propagation percentage and whether the results are consistent.”

Technical details

Endpoint

GEThttps://netintel-production-440c.up.railway.app/dns-propagation/check?utm_source=zero.xyz

When to prefer

Use this endpoint when you need to confirm that a DNS change (A, AAAA, MX, TXT, CNAME, or NS record) has propagated to the major public resolvers worldwide. It is the right choice when you want a propagation percentage and a consistency check across 10 named resolvers (Google, Cloudflare, OpenDNS, etc.) in a single call, rather than querying a single resolver or using a generic DNS lookup.

Side effects

Domain does not exist — resolvers return NXDOMAIN, propagation reported as 0%
Invalid domain format — returns validation error
Record type not found — resolvers return empty or NOERROR with no records
Network timeout to one or more resolvers — affected resolvers marked with failure status
Unsupported record_type value — returns error or defaults to A record
