Step-by-Step Workflow

4 Easy Steps
01Phase 1

Enter Domain Name

Type any root domain or subdomain (e.g., 'zerosuniverse.com') into the query bar.

02Phase 2

Select Record Type

Choose A, AAAA, MX, TXT, CNAME, or select 'All Core Records'.

03Phase 3

Trigger Live DoH Sweep

Click 'Query Live DNS' to dispatch parallel DNS-over-HTTPS requests.

04Phase 4

Inspect Resolvers & DNSSEC

Compare responses between Cloudflare, Google, and Quad9, and verify the DNSSEC AD flag.

Real-World Applications

Domain Migration

Verify whether updated IP addresses or CDN nameservers have propagated across major public resolvers.

Email Security Verification

Confirm SPF, DKIM, and DMARC TXT records are actively resolving without syntax errors.

DNSSEC Debugging

Diagnose 'SERVFAIL' errors caused by expired RRSIG signatures or broken parent DS delegations.
