IPvFooBarBaz is a Chrome extension developed by ziad87, falling under the Browsers category with a focus on Add-ons & Tools. This free extension serves as an enhancement of the original IPvFoo extension, offering real-time details of IPv4, IPv6, ASN, hostname, and HTTPS information for all page elements. It aims to provide users with insights into server IP addresses and related data, promoting awareness of the global IPv4 to IPv6 transition while also serving as a valuable developer tool for tracking request destinations.

The extension's action icon conveniently displays a red '4' or green '6' to indicate whether the outer page was fetched using IPv4 or IPv6, with additional indicators for connections to other domains. Upon clicking the icon, users can access a detailed table showcasing various information per domain, including IP addresses, connection types, and links to WHOIS, ARIN, RIPE, IPinfo, and bgp.tools for further exploration.
