DNS Record Lookup

DNS Propagation Checker

Enter the expected DNS record value to see which servers match ✅ or don't match ❌

Reverse IP Lookup

Provider: ViewDNS

Uses passive DNS / provider intelligence to show domains observed on an IP address. Results are not authoritative DNS data.

Use this when you want a provider-backed passive DNS view. This is not a live DNS query and it should not be treated as complete or authoritative.

Hosting Provider Lookup

Evidence-based Confidence rated

Estimate the DNS provider, CDN/WAF/edge layer, likely origin host, and mail provider from DNS, HTTP, TLS, PTR, and ASN evidence.

This tool intentionally says “likely” because CDN, WAF, and reverse-proxy layers can hide the real origin host.

WHOIS Domain Lookup

Pull registry WHOIS data with a cleaner registrar/date/status summary first, then raw output when you need the messy details.

SSL Certificate Check

301 Redirect Testing

Redirect Import Tester

Upload one or more 301 redirect import spreadsheets, combine them into one validation run, catch loops/conflicts, and export clean files before WordPress or WP Engine import.

Fixed-file exports
Ready: Upload redirect lists to catch import blockers before they hit WordPress or WP Engine.

HTTP Header Inspection

Repeatable header diagnostics with saved profiles, cache interpretation, CORS checks, and baseline drift comparison.

CORS / Preflight Diagnostics
Profiles and baselines use MySQL when available. Built-in profiles still work without saved custom profile storage.

HTTP Status Check

Run one-off checks or reusable launch smoke-test route sets with assertions and baseline drift history.

Expected Behavior and Route Set
One route per line. Format: URL/path | expected status | expected final URL | redirect count | title contains | body contains | body not contains | canonical URL

Port Scanner

TCP reachability checks with presets, service guesses, latency, and safer next steps.

Custom ports are added to the selected preset. Use commas, spaces, or ranges like 8000-8010.
Advanced Scan Options
Use this for authorized troubleshooting and firewall validation. Keep scans small and intentional.

Launch Readiness

Page Resource Audit

Scan one page for broken images, missing CSS/JS, failed resources, mixed content, redirects, slow assets, and staging/off-domain references before launch.

Advanced audit options
One pattern per line or comma-separated. Supports simple wildcards.
Used only for this scan and not included in exports/shares.

Domain Snapshot

Capture a broad domain-state snapshot with DNS, mail/auth records, SSL, registrar details, and edge-provider clues.

DNS Watcher

Create DNS watches quickly, then jump into a dedicated existing-watches view when you need to review active, recently alerted, matched, or failed watches.

Create Watch

New watches start here. If you already have watches, use the My DNS Watches button to review them without pushing this form down the page.

Advanced options
Preview
Fill out the form and click Preview Match to see how this watch will behave.
Grouped Multi-Condition Watcher Builder
Validation Bundle Builder
Validation Bundles
Create a bundle to group DNS, SSL, header, and status checks for one launch.
Launch Sessions
Launch Sessions tie baselines, validation bundles, scheduled snapshots, and a timeline together so one domain launch can be monitored from one place.
Launch Sessions
Create a launch session to coordinate scheduled snapshots, baselines, validation bundles, and timeline events.

Client DNS Handoff

Turn DNS changes into a polished private handoff page the client can actually follow, copy from, and update without back-and-forth confusion.

Client DNS Handoff workflow

Give the client one clean DNS packet instead of a wall of technical text.

Package the requested DNS changes into one private handoff page with clear instructions, copy-ready values, and current-versus-requested visibility that helps the client act without guesswork.

  • ✓One packet can hold every requested add, update, and remove action without burying the client in raw notes.
  • ✓Each DNS row can expose copy-ready host, value, and full-record actions so the client is not retyping by hand.
  • ✓Your team keeps the packet, client status, notes, and the latest live-DNS verification in one place.

Direct route: /handoff opens this tool immediately, just like /dns and /ssl.
Clear change instructions.Tell the client exactly what record action to take and why.
Copy-ready fields.Expose host, value, and full-record lines in one predictable place.
Live verification context.Show current DNS beside the requested end state with clearer wording.
What the client gets

A private handoff page with readable DNS rows, copy actions, a progress status, a note box, and the latest verification summary. No admin clutter. No unrelated tools. No guessing.

Best fit for launches, CDN cutovers, MX moves, domain onboarding, and any time the client controls their own DNS provider.

Build

Create a packet with clean add, update, and remove rows.

2

Share

Send one private link instead of a chain of screenshots and pasted DNS text.

3

Verify

Compare current live DNS against the requested end state with clearer wording.

4

Track

Keep status, notes, and verification history attached to the same packet.

📝 Reports

Build polished read-only outputs from saved launch workflows and the current visible result from any supported tool.

Use the new Report action on result panels for quick executive or technical outputs. This workspace handles saved launch sessions, validation bundles, and domain snapshot comparisons.
Saved workflow export

Validation Bundle

Generate a clean read-only report from one existing validation bundle.

Saved workflow export

Launch Session

Preserve the current launch-session state, timeline, and linked bundle context in one printable output.

Comparison export

Domain Snapshot Comparison

Choose two stored snapshots for the same domain and turn the comparison into a client-friendly read-only report.

Generated Reports

Ready for output

Generate a read-only report from a saved workflow or supported result panel.

When a report is ready, this area will show the preserved title, summary metrics, share state, and quick export actions.

DNS Zone File Compare

Paste or upload a DNS zone export and compare it against live DNS before a nameserver migration.

Text zone exports only. The file is read in this browser tab and sent as text for the comparison.

DNS Migration Readiness Workspace

Cutover planning Human review required

Combine live DNS, zone-file comparison, provider intelligence, proposed records, and watcher targets into one migration readiness review.

Used in the copy-ready client summary only.
Zone-file style lines work best. These become suggested post-cutover watcher targets.
This workspace does not change DNS. It creates a readiness checklist, migration summary, and watcher target suggestions to support the engineer’s final review.

Detects edge providers from live response headers first, then falls back to DNS and certificate hints when needed.
