Website DNS Checker — Web Hosting & CDN Records
Full DNS snapshot emphasizing A, AAAA, CNAME, and nameservers for website hosting verification
How to Use This Tool
- Enter the website hostname (apex or www).
- lookupAllDnsRecords queries A, AAAA, CNAME, NS, TXT, MX, and other types.
- summary.ipv4 and summary.ipv6 list hosting targets.
- summary.cnameTarget shows alias destinations when CNAME exists.
- nameservers and byType group full zone context.
- queriedAt timestamps the snapshot for change tickets.
About This Tool
Website availability depends on correct A, AAAA, and CNAME records pointing at your host or CDN — not just whether the domain resolves somewhere. VSPIC website DNS checker uses the dns-history action with lookupAllDnsRecords, returning records, byType, summary with ipv4, ipv6, cnameTarget, nameservers, queriedAt, and a note that historical years require saved snapshots.
Operators use this page before go-live, after CDN migrations, or when SSL errors coincide with DNS changes. Mail authentication TXT appears in the same snapshot — useful holistically but this copy emphasizes web routing fields in summary.
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 ?
- Web-focused summary fields atop full zone data.
- IPv4 and IPv6 targets in one click.
- CNAME chain visibility for CDN cutovers.
- Nameserver context for delegation issues.
- queriedAt for go-live evidence.
- Free read-only check — same API as DNS monitoring.
Website DNS versus mail DNS in one snapshot
lookupAllDnsRecords returns the full public zone — web and mail records together. Website DNS checker copy emphasizes A, AAAA, CNAME, and NS because those drive HTTP routing.
SPF and DMARC in summary still matter if the same domain sends mail — do not ignore TXT when only testing web go-live.
Reading summary.ipv4, ipv6, and cnameTarget
ipv4 and ipv6 arrays list address targets for the name queried. cnameTarget surfaces the first CNAME destination when aliasing to a CDN or hosting platform.
Apex apex-to-www redirects may use A at apex and CNAME at www — check both hostnames separately.
CDN and CNAME cutover verification
Migrating to Cloudflare, Fastly, or vendor CNAME targets changes cnameTarget or A to anycast ranges. Snapshot before and after cutover; compare ips against vendor documentation.
TTL on old A records affects how long clients hit previous hosting after successful DNS panel edits.
Nameservers and website DNS
nameservers in results show which DNS host serves the zone. NS at registrar must delegate to this host — correlate with whois-dns-lookup trace when site fails after transfer.
Wrong NS at TLD while panel shows correct A records is a classic post-migration failure mode.
IPv6 and dual-stack hosting
summary.ipv6 empty on dual-stack hosts warrants AAAA investigation — some users reach site only via IPv6. Missing AAAA is not always intentional.
Pair with DNS compare when staging and production should mirror both stacks.
Go-live and rollback documentation
Export snapshot with queriedAt at go-live approval. Rollback runbooks restore A and CNAME from export if new host misconfigured.
Attach JSON to change tickets permanently for audit.
Relationship to dns-monitoring-tool
Both call dns-history. Website DNS checker emphasizes hosting verification language; DNS monitoring emphasizes scheduled drift detection. Identical JSON — choose page by workflow.
Use domain-dns-audit when comparing staging versus production side by side.
What this check does not do
No HTTP status, redirect chain, or certificate validation. Site may DNS-resolve while origin returns 502.
Use SSL checker and redirect tools for application-layer go-live checks.
API action dns-history
GET /ip-tools/api/extended?action=dns-history&domain=www.example.com returns full snapshot. Automate post-deploy website verification in CI.
Parse summary.ipv4 and cnameTarget for pipeline gates.
Privacy and responsible use
Website DNS is public. Query domains you own or administer.
Snapshots may include verification TXT — handle exports carefully.
Important notes & limitations
- Does not HTTP-fetch the site or validate TLS certificates.
- CDN anycast may geo-steer — one resolver path shown.
- Wildcard expansion not explicit — compare random subdomain separately.
- Historical months require saved exports — not automatic archive.
- Internal split-horizon DNS may differ from public results.
Frequently Asked Questions
Yes. VSPIC offers this website DNS checker 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.
Check the hostname users type in browsers. Many sites need both apex and www snapshots.
No. DNS only. Use browser or uptime tools for HTTP/TLS verification.
dns-history with a domain parameter — same backend as DNS monitoring tool.
lookupAllDnsRecords returns the full zone. Mail records appear but web summary fields are highlighted here.
Only if you saved a snapshot last year. This captures current public DNS at query time.
CDNs proxy via anycast edges. A records may show CDN ranges, not your origin — expected when proxied.
