IP DNS Whois viewer by Sitte.pl

IP Viewer is a lightweight Firefox extension that displays the visited site’s IP address in real time using both the webRequest API and a DNS fallback mechanism. The extension provides comprehensive details such as WHOIS information, domain data, and tracking code identifiers (including Google Analytics [both UA and GA4], Google Tag Manager, Clarity, and Facebook Pixel). It also offers quick access to external tools like SSL Checker and DNS Info, and includes a built-in refresh feature to update information instantly.

Designed with a sleek, modern interface featuring a stylish look and support for multiple languages, IP Viewer is ideal for developers, system administrators, and privacy-conscious users. Its open-source nature and secure implementation ensure that all dynamic content is safely sanitized for optimal performance and reliability.
