What is WHOIS?

On my recent post title substitute of dot.com I mentioned about secure identity when using .WS and instead of .com.

To see and as to believe what I am talking about, click this link (http://www.ip-adress.com/whois/www.miguelglobal.ws) my registered domain name has no details to offer. Then try to type any domain name of yours with .com and you will be surprise knowing your information are very detailed in WHOIS.

What is WHOIS?

WHOIS (who is) is the aptly named Internet function that allows one to query remote WHOIS databases for domain registration information. By performing a simple WHOIS search you can discover when and by whom a domain was registered, contact information, and more. A WHOIS search can also reveal the name or network mapped to a numerical IP address. Originally, WHOIS searches were performed in a command line environment and took the form, [drive]:\>whois domain.com. Searches can still be performed from the command line, but Web interface tools now make it convenient to visit a WHOIS website and simply enter the IP address or domain name.

In the case of a privately owned domain, the WHOIS database contains the full name, address, telephone number, and email address of the registered owner of the domain. If the domain is owned by a business, the company name, address, email, and telephone number are listed. There are also fields for a domain administrator, technical administrator, and other contacts. The expiration date of the registration period is also listed.

While the original purpose of the WHOIS database was to provide a directory for domain owners, the publicly available information opened the doors to mass spam and other abuses. The terms and conditions of WHOIS databases include a provision that the information revealed shall not be used for such purposes, but this has proven to be a rather anemic solution. To further discourage data miners, most WHOIS sites have implemented a script with a random graphic display of numbers or letters which the requester has to manually enter into a field. "Bots" or data scouring programs cannot read these graphic displays, disabling results from automated queries. Beyond precautions such as these, there is no real mechanism in place to catch, identify, or punish abusers of WHOIS information.
