DNS Record Lookup

Introduction

You use WHOIS to discover who registered a domain, when it was created, and when it expires. The protocol stores public contact and status data on accredited servers.

This tool queries those servers over HTTPS, then highlights registrar, nameserver, and date fields in a tidy, single‑page display. Nothing installs; results appear seconds after you click.

Check renewal deadlines before you lose a name, or confirm a seller’s ownership record during due diligence. Always verify critical legal details with the official registry.

Technical Details:

The client runs entirely in your browser, using a lightweight reactive interface. It fetches WHOIS JSON from a third‑party endpoint through an HTTPS proxy, parses the payload locally, and renders two synchronized views.

Domain Validation

The input checks RFC‑1035 syntax before any request. Example: enter example.com and see instant acceptance. Caution: labels exceeding 63 characters are rejected.

Progress Feedback

A spinner and “Looking up WHOIS data…” alert show request status. Example: slow networks still reassure users. Caution: closing the tab cancels the fetch silently.

Tabbed Data Views

Toggle between Info and JSON tabs. Example: copy registrar in the visual list, then inspect raw timestamps. Caution: large zone files may truncate for readability.

Clipboard Helpers

Copy any field or the full record with one click, using the secure Clipboard API. Example: paste dates into spreadsheets instantly. Caution: older browsers fall back to hidden text areas.

Local Download

Create a JSON file in memory and prompt a save dialog. Example: archive example.com.json for audits. Caution: mobile browsers may store files in unpredictable locations.

Step-by-Step Guide:

Follow these quick steps to retrieve a full WHOIS record.

1. Type the target name into the Domain input field. Tip
2. Press the Lookup button or hit Enter.
3. Wait until the “Looking up WHOIS data…” notice disappears.
4. Review key fields under the Info tab.
5. Switch to the JSON tab for the raw response.
6. Click Copy JSON or Download JSON to reuse the data.

Troubleshooting:

Resolve common issues quickly.

• “Lookup failed.” — Check your internet connection or disable content blockers that intercept cross‑origin requests.
• “Domain is required.” — Enter a name like example.com first.
• “Enter a valid domain.” — Remove protocol prefixes and trailing slashes.
• Spinner never stops — The registry may be rate‑limiting; wait a minute and try again.
• Download button unresponsive — Mobile browsers sometimes block file saves; use desktop for archiving.

Advanced Tips:

Level‑up your workflow with these hints.

• Bookmark the page with a query string (e.g., ?domain=example.com) to preload lookups.
• Use the JSON tab with command‑line utilities for batch analysis.
• Monitor expiry dates by exporting data to calendar reminders.
• Combine WHOIS output with DNS records for complete audits.
• Enable dark mode via your operating‑system preference for reduced eye strain.
