DNS Resolver Finder — Nameserver & DNS History Lookup

Discover authoritative nameservers and live DNS records for any domain via dns-history lookup

How to Use This Tool

  1. Enter domain name in the domain field.
  2. Server calls action dns-history with lookupAllDnsRecords.
  3. Returns records array and byType grouping.
  4. nameservers lists authoritative NS hostnames for the zone.
  5. summary includes hasSpf, hasDmarc, mailServers, ipv4, ipv6.
  6. emailAuth shows SPF and DMARC strings when published.

About This Tool

Developers debugging resolution paths and security auditors inventorying who answers DNS for a zone search DNS resolver finder for recursive resolver IPs, authoritative nameservers, and upstream DNS providers. VSPIC DNS resolver finder calls the dns-history action with domain field — lookupAllDnsRecords returning structured records, byType grouping, nameservers array, summary flags, mailServers, ipv4, ipv6, emailAuth SPF and DMARC strings, queriedAt timestamp, and note about passive history archives.

missing-tools-handlers.generated.ts maps dns-resolver-finder to type api, action dns-history — live zone snapshot, not your local workstation recursive resolver IP (use ipconfig DNS Servers for that). This page documents dns-history behavior honestly: authoritative NS and full record inventory for domains you query, distinct from client-side resolver discovery.

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 ?

  • Full zone snapshot with authoritative nameserver identification.
  • byType grouping speeds A, AAAA, MX, NS, TXT review.
  • summary flags accelerate mail and auth posture checks.
  • Same dns-history backend as dns-security-audit pages.
  • Free instant lookup — no account required.
  • queriedAt timestamp documents evidence time for tickets.

Authoritative nameservers versus recursive resolvers

Authoritative nameservers — listed in NS records — hold canonical zone data. Recursive resolvers — 8.8.8.8, 1.1.1.1, or ISP DNS — cache and forward queries on behalf of clients. missing-tools-handlers.generated.ts maps dns-resolver-finder to action dns-history returning authoritative NS and full records for the domain you enter.

To find your local recursive resolver, run ipconfig DNS Servers on Windows or cat /etc/resolv.conf on Linux.

What dns-history action returns

lookupAllDnsRecords fetches live DNS for the domain: records, byType, nameservers, summary with hasSpf hasDmarc mailServers ipv4 ipv6, emailAuth, queriedAt, note.

GET /ip-tools/api/extended?action=dns-history&domain=example.com.

Identifying DNS hosting provider

NS hostnames reveal provider — ns-cloud-a1.googledomains.com suggests Google Domains DNS, dns1.p01.nsone.net suggests NS1. dns-hosting-provider-finder page targets similar workflows.

Compare NS against registrar WHOIS — delegation mismatch causes resolution failures.

Recursive resolver discovery locally

Windows: ipconfig /all DNS Servers. macOS: scutil --dns. Linux: resolvectl status or /etc/resolv.conf. Router admin shows DHCP-assigned DNS to LAN clients.

Document local resolver in gateway-finder scratchpad — not via dns-history API.

Relationship to dns-security-audit

Both call action dns-history with identical JSON. dns-security-audit emphasizes security audit language; dns-resolver-finder emphasizes nameserver and resolver infrastructure search vocabulary.

Relationship to recursive-dns-checker

recursive-dns-checker tests open resolver amplification risk on IPv4 — different action from zone snapshot. Use both when hardening DNS posture: zone inventory here, open resolver scan there.

Mail and auth in summary

summary.mailServers and emailAuth SPF DMARC strings support deliverability review alongside NS identification. MX targets may differ from web hosting A records.

API automation for NS drift

Schedule weekly dns-history calls per domain. Diff nameservers arrays between exports — unexpected NS change may indicate hijack or migration.

Store queriedAt with each export for compliance evidence.

Responsible use

Query domains you administer or have authorization to audit. dns-history performs live DNS lookups without storing your searches permanently.

Important notes & limitations

  • Does not report your PC or router recursive resolver IP.
  • Live snapshot only — not multi-year passive DNS timeline.
  • note field clarifies archive limits without saved snapshots.
  • Authoritative NS discovery — not recursive resolver path tracing.
  • DNSSEC chain validation requires dedicated DNSSEC tools.

Frequently Asked Questions

Yes. VSPIC offers this DNS resolver finder 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 returns authoritative nameservers and zone records via dns-history. Use ipconfig DNS Servers locally.

The NS records published for the domain you enter — authoritative servers, not 8.8.8.8 unless Google hosts your zone.

Same action dns-history and JSON backend. Different SEO page framing.

Live snapshot with note about passive archives. Schedule exports for your own history timeline.

Enter the zone apex or subdomain — dns-history queries live DNS for that name.
