Understanding WHOIS Data

WHOIS data provides public information about domain name registration. However, due to privacy regulations (like GDPR) and privacy protection services offered by registrars, contact information for the domain owner may be redacted or replaced with proxy details.

How to Use This Domain WHOIS Tool

  1. 1

    Enter Domain Name

    Type the domain name you wish to query into the input field (e.g., showmyip.com).

  2. 2

    Submit Your Query

    Click the "Lookup" button. Our tool will connect to the appropriate WHOIS server for the domain's Top-Level Domain (TLD).

  3. 3

    Analyze the Results

    Review the raw WHOIS data returned by the registry. We also provide a parsed view highlighting key information like registrar, creation/expiration dates, and name servers for easier analysis.

Understanding Domain WHOIS Results

The WHOIS database contains public records associated with domain name registrations. Here's what key pieces of information mean:

Registrar Information

Details about the company that registered the domain name for the owner. This includes their name and often a WHOIS server address specific to that registrar.

Registration Dates

Important dates related to the domain's lifecycle: creation date (when it was first registered), updated date (last modification), and expiration date (when the registration needs renewal).

Name Servers (DNS)

The servers that translate the domain name into an IP address. These are crucial for the domain to be accessible on the internet.

Contact Information

Details for the registrant (owner), administrative, and technical contacts. Due to privacy rules (like GDPR) or privacy services, this information might be redacted or show proxy details.

Domain Status

Indicates the current state of the domain (e.g., clientTransferProhibited, ok). These statuses can affect whether a domain can be transferred, renewed, or if it's pending deletion. Learn more about EPP status codes.

Frequently Asked Questions About Domain WHOIS

What is WHOIS?

WHOIS is a query and response protocol used for querying databases that store the registered users or assignees of an Internet resource, such as a domain name, an IP address block, or an autonomous system number. It provides public access to registration information.

Why is some WHOIS contact information hidden?

Many domain owners use WHOIS privacy protection services offered by their registrars. These services replace the owner's actual contact information with proxy details from the privacy provider. Additionally, regulations like the GDPR (General Data Protection Regulation) in Europe restrict the public display of personal data, leading registrars to redact contact information for individuals.

How accurate is WHOIS information?

Registrants are generally required by ICANN (Internet Corporation for Assigned Names and Numbers) policies to provide accurate contact information. However, the accuracy depends on the registrant updating their details and whether privacy protection is used. While technical details like name servers and dates are usually accurate, contact information validity can vary.

Can I find out who owns a domain if their information is private?

Generally, no. WHOIS privacy services are designed to prevent public disclosure of the owner's identity. You might be able to contact the owner through a contact form provided by the privacy service, but their direct details are typically not revealed through a standard WHOIS lookup. Legal channels may be required for legitimate disputes.

What does the 'Domain Status' mean?

Domain status codes indicate the state of a domain registration. Common statuses include 'ok' (active, no restrictions), 'clientTransferProhibited' (locked against transfer), 'redemptionPeriod' (expired but can be recovered at extra cost), and 'pendingDelete' (expired and about to be released). You can find a full list of EPP status codes on the ICANN website.

Common Uses for Domain WHOIS Lookups

Performing a WHOIS lookup can be useful in various situations:

Checking Domain Availability

While not a definitive check, a WHOIS lookup can indicate if a domain is already registered. If no record is found, the domain might be available (though confirm with a registrar).

Identifying Domain Owners

Find out who registered a specific domain name for business inquiries, contact purposes, or research (subject to privacy limitations).

Network Troubleshooting & Security

Network administrators and security professionals use WHOIS data to trace the origin of network activity, investigate malicious domains, or verify registration details.

Trademark & Legal Issues

WHOIS lookups can be a starting point for identifying domain owners in cases of trademark infringement or other legal disputes related to domain names.

About Domain WHOIS Lookup

What does this tool do?

Our Domain WHOIS Lookup tool reveals detailed registration information about any domain name. It queries WHOIS databases to show the domain registrar, creation and expiration dates, name servers, and contact information (when publicly available).

Why is this useful?

Domain WHOIS data helps verify domain ownership, check expiration dates, find contact information for legitimate business purposes, investigate potential fraud, and understand domain history. It's essential for business research, legal compliance, and security investigations.

Who uses this tool?

  • Business professionals - Research potential partners, verify company domains, and check domain availability
  • Legal professionals - Investigate trademark infringement, identify domain owners for legal proceedings
  • Security analysts - Track malicious domains, investigate phishing sites, and analyze threat sources
  • Domain investors - Research domain history, check expiration dates, and identify acquisition opportunities
  • Web developers - Verify client domains, check DNS settings, and troubleshoot domain issues

How to perform a domain WHOIS lookup

  1. Enter the domain name you want to research (without http:// or www)
  2. Click "Lookup" to query the WHOIS database
  3. Review the key information displayed in organized sections
  4. Check domain status, name servers, and contact details
  5. Note expiration dates and registrar information

Example

Looking up google.com shows it's registered through MarkMonitor Inc., created in 1997, and uses Google's own name servers. The domain status indicates it's active and properly configured.

Understanding your results

Domain Name
The exact domain name as registered in the WHOIS database.
Registrar
The company authorized to register and manage this domain name.
Creation Date
When the domain was first registered and added to the DNS system.
Expiration Date
When the domain registration expires and must be renewed to remain active.
Name Servers
The DNS servers responsible for resolving this domain to IP addresses.
Domain Status
Current status codes indicating the domain's operational state and any restrictions.

Common Domain Statuses

  • clientTransferProhibited: Domain transfers are locked by the registrar
  • clientDeleteProhibited: Domain deletion is prevented for security
  • clientUpdateProhibited: Domain information updates are restricted
  • serverHold: Domain is suspended and not resolving

Privacy considerations

  • Privacy protection: Many domains use privacy services that hide owner contact details
  • GDPR compliance: European domains may show limited information due to privacy regulations
  • Recent changes: Some registrars no longer display personal contact information publicly

Important notes

  • WHOIS data accuracy depends on information provided by domain registrants
  • Some domains may have privacy protection enabled, limiting visible information
  • Contact information shown may be for the registrar rather than the actual domain owner
  • Data freshness varies - some registries update more frequently than others

Common use cases

Business Research

Verify company domain ownership, check business legitimacy, and research potential partners or competitors in your industry.

Domain Management

Monitor expiration dates to prevent domain loss, verify DNS settings, and track changes to domain registration information.

Security Investigation

Investigate suspicious domains, track malicious websites, and gather intelligence on potential security threats or phishing attempts.

Legal Compliance

Support trademark investigations, identify domain owners for legal proceedings, and ensure compliance with intellectual property rights.

Privacy and responsible use

While WHOIS information is publicly available, it should be used responsibly and legally. Respect privacy rights, comply with anti-spam laws, and use this information only for legitimate business, security, or legal purposes.
