How this service works
Every DNS record for a domain plus propagation across public resolvers
Output
Returns the DNS records of the requested type for the domain as seen by multiple public resolvers, showing the record values each resolver returns so you can identify propagation consistency or discrepancies across the global DNS infrastructure.
Example use cases
Verify DNS propagation after migration
“I just moved example.com to a new host and updated the A record — can you check across public resolvers whether it's fully propagated yet?”
Debug inconsistent email delivery
“Our email is acting weird — can you pull the MX records for mybusiness.com across multiple resolvers and tell me if they all agree?”
Confirm TXT record for domain verification
“I added a TXT record to verify mysite.com for Google — can you check what the public resolvers are seeing for that domain's TXT records to make sure it's live?”
Technical details
Endpoint
GEThttps://sentinel.rootstuff.io/x402/dnsWhen to prefer
Choose this endpoint when you need to audit DNS record propagation across multiple public resolvers simultaneously rather than querying a single authoritative server. It is ideal for post-migration verification, debugging mail delivery issues tied to MX records, confirming TXT record visibility for domain ownership proofs, or investigating why some users see different results than others due to DNS caching inconsistencies.
Side effects
- Invalid domain name returns an error or empty result
- Unsupported record type string causes a bad request
- Domain does not exist (NXDOMAIN) across all resolvers returns empty or NXDOMAIN responses
- Resolver timeouts may cause incomplete propagation data
- Newly registered domains may return inconsistent or empty results during initial propagation
