DNS Query Generator — Multi-Type Lookup Output

One domain in — complete multi-QTYPE query output with byType grouping and summary

How to Use This Tool

  1. Enter the domain to generate query output for.
  2. Hostname is validated and normalized to lowercase apex or FQDN form.
  3. Parallel lookups run for nine common record types via public DNS.
  4. Each successful answer appends to records and byType buckets.
  5. summary compiles ipv4, ipv6, mailServers, SPF/DMARC flags, and NS list.
  6. Export JSON or call dns-history API for scripted generation pipelines.

About This Tool

Writing dig scripts for every record type during migrations is tedious — operators want generated query output they can paste into runbooks or diff tools. VSPIC DNS query generator runs the dns-history action: lookupAllDnsRecords fires parallel queries for A, AAAA, MX, TXT, NS, CNAME, SOA, SRV, and CAA against your domain and returns records, byType, summary, nameservers, emailAuth hints, and queriedAt in one JSON-shaped response.

Use output as generated query results for documentation templates, Terraform validation checklists, or onboarding packets listing every public RR the internet sees. The generator does not emit dig command strings — it performs the queries server-side and returns answers, which is faster than hand-running nine QTYPE commands.

Common use cases

  • •View all DNS records of a domain after migration
  • •Confirm DNS records after domain changes
  • •Test for DNS leaks when using a VPN
  • •Debug email delivery with MX and TXT records

Why use VSPIC for ?

  • Nine QTYPE sweep generated in one click — no manual dig loop.
  • byType output ready for templates and diff scripts.
  • summary block for executive summaries and ticket attachments.
  • queriedAt anchors generated output to a point in time.
  • Free generation with no account or API key for casual use.
  • Consistent shape with DNS record history for automation reuse.

What DNS query generation means here

Some tools emit dig command lines you still run locally. Our generator executes the query plan server-side and returns structured answers — the generated artifact is the DNS data itself, grouped for immediate use in spreadsheets, CMDB imports, or JSON schema validators.

Generation covers the QTYPE set most runbooks require during cutover: address, mail, text, delegation, alias, start-of-authority, service, and CA authorization records.

lookupAllDnsRecords as the generator engine

The dns-history backend calls Google Public DNS JSON API per type in parallel. Failures for individual types are skipped rather than failing the whole generation — partial output still documents what public resolvers publish.

DMARC is fetched from _dmarc subdomain TXT when present, folded into summary alongside apex TXT SPF detection.

Using byType in generated documents

Paste byType.A into hosting verification tables. byType.MX feeds mail migration worksheets with priorities intact. byType.TXT consolidates SPF, DKIM, and verification strings for receiver-side review.

Empty arrays prove negative answers — important when proving a record type was intentionally removed.

summary for stakeholder packets

Non-DNS stakeholders read summary.ipv4 and summary.hasSpf faster than raw RR lists. Include summary in generated PDFs while attaching full records for engineering.

nameservers in summary should match registrar delegation before sign-off — mismatch triggers trace tools before go-live.

Automation with dns-history API

GET /ip-tools/api/extended?action=dns-history&domain=example.com returns the same generated shape. Loop domains from inventory CSV in CI and fail builds when required summary flags flip unexpectedly.

Store generated JSON as artifacts named domain-queriedAt.json for reproducible audits.

Migration query generation checklists

Pre-migration: generate output at old provider. Post-migration: regenerate and diff. Query generator output becomes the acceptance test definition — every RR class documented.

Include CAA in generation when TLS certificate automation depends on issuer restrictions — missing CAA in output means public path sees none.

Relationship to DNS lookup and record history

Single-type lookup tools query one QTYPE interactively. Generator sweeps all common types at once. DNS record history shares identical backend — this page targets generate-all-output search intent.

DNS query simulator page also uses dns-history with simulation-oriented language for training scenarios.

Limits versus custom QTYPE labs

Labs needing DNSKEY, CDS, or LOC types must use dig or specialized APIs. Generator optimizes operational QTYPE coverage, not DNSSEC key material or experimental RR types.

Generated output reflects one resolver vantage — multi-region generation requires external synthetic monitoring.

Privacy and responsible generation

Generated TXT may expose verification tokens and SPF includes revealing third-party vendors. Redact before sharing externally.

Generate only for domains you administer or audit under contract.

Important notes & limitations

  • Generates answers, not literal dig/bash command strings.
  • Public resolver path only — internal split-horizon differs.
  • Does not generate reverse (PTR) or custom TYPE255 queries.
  • No AXFR — hidden authoritative records may be missing.
  • Rate limits apply on high-volume API generation jobs.

Frequently Asked Questions

Yes. VSPIC offers this DNS query generator at no cost with no account required. Results load in real time.

We do not permanently store your queries on our servers. Some tools run entirely in your browser; others fetch public data for the request only.

Yes. Open the page in any modern phone or tablet browser. Results work on Wi‑Fi and mobile data.

No. It runs queries and returns structured answers. Use the JSON as generated query results.

dns-history with a domain parameter.

A, AAAA, MX, TXT, NS, CNAME, SOA, SRV, and CAA when present on the public path.

Yes. Call the extended API with action dns-history per domain. Respect rate limits.

No public answer was returned for that QTYPE — NXDOMAIN or empty NOERROR for that type.

Same dns-history backend. Generator emphasizes documentation output; simulator emphasizes training and what-if resolver behavior language.
