Reverse IP Lookup

Provider: ViewDNS

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

IP Address

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.

Domain or Hostname

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

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.
