WHOIS Search is a Chrome extension developed by jarno.j.niemela that allows users to quickly perform WHOIS lookups on selected text from web pages. This handy tool is especially useful for those who frequently work with IP addresses and domain names.

With WHOIS Search, users can simply select an IP address or word on a web page, right-click their mouse, and choose "WHOIS " from the context menu. The extension will then perform a WHOIS lookup on the selected text, providing information about the IP address or domain.

One of the standout features of WHOIS Search is its ability to search for .com address availability when a word or text is selected instead of an IP address. This feature makes it easy to check if a specific domain name is available for registration.

Developed by jarno.j.niemela, WHOIS Search utilizes the Whois.com service for its lookups. The extension is available for free on the Chrome platform and falls under the category of Browsers with a subcategory of Add-ons & Tools.

Overall, WHOIS Search is a valuable tool for anyone who frequently works with IP addresses and domain names. Its simple right-click interface and integration with Whois.com make it convenient and efficient for performing WHOIS lookups.
