Check-Host Quick Lookup

About

It is an easy-to-use browser extension that allows you to verify and analyze IP addresses or domain names you see on any web page in seconds. With its right-click menu and modern popup interface, it offers quick diagnosis capabilities to a wide audience, from system administrators to security researchers.

Key Features

- One-click verification: Right-click on your selected IP address or domain name and use the “Check-Host.net” option; results open immediately in a new tab.

- Smart input validation: IPv4 addresses and domain names are automatically checked, displaying user-friendly warnings for incorrect entries.
 
- Powerful popup experience: Manually enter data, access your query history, copy or reopen queries—all on a single screen.

- Local history management: Up to 8 queries are stored on your device; data is kept entirely in your browser's local storage.

- Multilingual interface: The interface automatically adapts if your browser language is English or Turkish.

 - Optional measurement: Thanks to GA4 Measurement Protocol integration (when you add the API secret), you can collect usage metrics that do not contain personal information.
