## Overview

The WHOIS Lookup tool provides instant access to domain registration details, allowing you to verify ownership information, registrar data, expiration dates, and DNS name servers for any registered domain.

## Inputs

- **Domain Name** (text): Enter domain name (e.g., google.com)
- **Include Raw WHOIS Data** (checkbox)

## When to use

- Verify the registration status and expiration date of a domain name.
- Identify the official registrar and associated name servers for technical troubleshooting.
- Check domain availability or research ownership details for potential acquisitions.

## How it works

- Enter the target domain name into the input field.
- Select the option to include raw WHOIS data if you require the complete, unparsed registry response.
- Click the lookup button to retrieve and display the registration information.

## Use cases

- Verifying domain expiration dates to prevent accidental service outages.
- Troubleshooting DNS configuration issues by checking assigned name servers.
- Conducting due diligence before purchasing a domain from a third party.

## Frequently asked questions

### What information does a WHOIS lookup provide?

It typically returns the registrar, registration and expiration dates, name servers, and the current status of the domain.

### Can I see the owner's personal contact details?

Most modern domains use WHOIS privacy services, which mask personal contact information with the registrar's generic details.

### What is the difference between standard and raw WHOIS data?

Standard output provides a clean, summarized view, while raw data includes the full, unformatted response directly from the registry.

### Is this tool free to use?

Yes, you can perform unlimited WHOIS lookups for any public domain name without cost.

### Why does a domain show as 'not found'?

This usually means the domain is not registered, or the registry does not support public WHOIS queries for that specific TLD.
