How this service works
Resolves A, CNAME, MX, and TXT DNS records globally via isolated public resolvers with DNS rebinding protection.
Output
Returns the resolved DNS records for the specified domain and record type (A, CNAME, MX, or TXT), fetched through isolated public resolvers with DNS rebinding protection. Results include the record values (e.g. IP addresses for A records, mail server hostnames for MX, raw strings for TXT, canonical names for CNAME).
Example use cases
Verify SPF record for email deliverability
“Check the TXT records for example.com — I want to see if it has a valid SPF record set up for email deliverability.”
Find IP address of a domain
“What IP address does api.github.com resolve to? Look up its A record right now with a live DNS query.”
Confirm CNAME target for subdomain
“I need to check what CNAME target docs.mycompany.com is pointing to — can you resolve that DNS record?”
Technical details
Endpoint
POSThttps://dt0ur.online/api/network/dns?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need reliable, globally-consistent DNS resolution with DNS rebinding protection — particularly useful in agentic or automated contexts where security matters. Prefer this over raw system DNS when you need isolated resolution (avoiding local cache or split-horizon DNS), when you need to force a live query bypassing cache, or when you need to query specific record types (A, CNAME, MX, TXT) programmatically in a workflow.
Side effects
- Domain does not exist (NXDOMAIN) — returns error indicating no such domain
- Requested record type not present for domain — returns empty or no-records response
- DNS rebinding attempt detected — blocked by protection layer
- Invalid or malformed domain input — returns validation error
- Resolver timeout or network failure — returns error after timeout
