WHOIS lookup is a browser-based query and response tool that searches a domain name's publicly available registration and delegation details across the various public WHOIS databases.
To view the WHOIS details for a domain name, type the domain name you want to look up into the search box found above, and press the button marked WHOIS Lookup.
If you are querying an Australian domain name it will be necessary to complete the CAPTCHA code that appears after pressing the WHOIS Lookup button.
The WHOIS domain database gives users the ability to quickly and easily check important information about a particular domain name, including the registration status, ownership details, and whether the registrant information is up to date.
The WHOIS domain database is used to query database that store the registered users or assignees of an Internet resource, such as a domain name, an IP address block or an autonomous system, but is also used for a wider range of other information.
The information presented in the WHOIS domain database reflects data that is managed by your current domain name registrar. This is most commonly the business who you registered your domain name with and can be confirmed by performing a WHOIS lookup and referring to the 'Registrar' field.
The Internet Corporation for Assigned Names and Numbers (ICANN) is a nonprofit organisation who oversee the policies and procedures surrounding domain names, DNS, and the many namespaces of the Internet.
ICANN policy requires that specific data is provided when registering a domain name and that this personal information is then stored by the registrar in what is known as a WHOIS record.
To prevent your personal details from being made publicly available via WHOIS lookup you will need to contact the registrar that currently manages your domain name and request that they offer a Whois Privacy product such as ID Protection.
It's important to note that due to Registry policy, some of the most popular domain names (such as .com.au) do not allow the use of Whois Privacy services.
If a WHOIS lookup is performed on a specific domain name and the results presented show 'not found' then it is likely that the domain name has not yet been registered and is available for registration.
