Once people discover about WHOIS, many of them become curious to find information about their competitors. Using WHOIS Google plugins or online checkers can show you if your competitors are going to use new technologies or move to another provider , maybe, for scaling. In this article, we will highlight some tools to find all WHOIS information.
If you have used the IP Whois & Flags Chrome & Websites Rating extension, you may have noticed that Chrome no longer supports it. This is because Google has introduced a new version of its extension platform, Manifest V3 . Although plugin developers had enough time to transition to the new standard, Myip.ms did not do so, and the extension became unavailable.

Web developers, SEO specialists, analysts, and even ordinary users may need tools to determine the technical characteristics of websites. This is useful because it allows you to choose high-quality virtual hosting or other necessary services for optimizing your own website based on the example of functional web resources.
With IP Whois & Flags Chrome, you could find out the IPv4 and IPv6 addresses of a website, its location, number of visitors, and other useful information. Due to its blocking, users are forced to switch to alternative plugins, and we are ready to offer you decent options.
What has changed since the deployment of Manifest V3?
Manifest V3 is a new version of the API for Chrome extensions, aimed at improving performance and security. It reduces the flexibility of plugins but provides greater data privacy. Extensions that have not migrated to the third version of the manifest will stop working or will be removed from the Chrome Web Store.
Key changes compared to Manifest V2
Manifest V3 includes several new requirements that extensions must adapt to, including:
- Service workers have replaced background pages. Extensions now work as background scripts that run only when needed, rather than constantly.
- Declarative network requests. The webRequest API has been replaced with declarativeNetRequest, so extensions can no longer intercept and modify HTTP requests. This reduces their flexibility but improves performance and privacy.
- Prohibition of remote code usage. Developers can no longer use remotely hosted code. All updates must undergo moderation, which can take several weeks.
