About Whois Checker

WHOIS checker is an information collection tool that allows you to access the WHOIS database, which is the public directory for information about registered domain names. All domain providers require the domain owner to provide contact information to the domain registrar based on ICANN rules. The contact information will appear in the WHOIS checker search results.

What is WHOIS?

WHOIS stands for World Wide Web Internet Domain Name System. It is a database system that provides information about domain names and their owners. You can use it to find out who owns a website address, who hosts the website on its servers, and even whether a website is registered under a different name.

The WHOIS checker tool is a free service provided by ICANN (Internet Corporation for Assigned Names and Numbers) that we provide to you to let you search for and view details about any domain name registration.

When you register a domain name, Internet Corporation for Assigned Names and Numbers (ICANN) requests that your domain name registrar sends personal contact information to the WHOIS database. Once your list appears in this online domain WHOIS directory, anyone who has chosen to use the WHOIS search tool to check the domain name can get that list to the public.

WHOIS search results include:

  • Domain owner contact information
  • Registrar information.
  • The registration date, the most recent update date, and the expected expiration date.
  • Name Server Information
  • Current status of domain name

Use Cases for a WHOIS checker 

Incident response and threat intelligence - For those responding to security incidents; the most apparent benefit of the WHOIS checker is identifying the netblocks and ISPs that own a particular IP address. From this information, incident responders can contact the netblock owner and alert the provider of the presence of malicious traffic.

One can use the Historical WHOIS records to search for details on WHOIS data that a responder may have across multiple investigations or targets. For example, you can search your WHOIS data to find e-mail addresses that span multiple domains and determine when the e-mail addresses first appear in your WHOIS records.

Using WHOIS to troubleshoot network problems

By accessing WHOIS data, network engineers may be able to examine the paths on the Internet and notice that specific networks are causing significant delays. Online WHOIS searches enable network engineers to identify the owner of a network in question and contact the engineer responsible for that network.

Finding other IP information 

Searching the WHOIS database for an IP address is practical to find out who has the IP address, if it already exists, and to provide other data. However, in some cases, you may need to find an IP address from your domain to search with the WHOIS search tool. To find an IP address from a domain name, use IP address reverse or DNS reverse to search for URLs from IP addresses.
