Domain/IP Info Lookup od networkluki

This Firefox extension lets you enter a domain or IP address and view technical information directly inside the extension. If you enter a domain, the extension first attempts to resolve its IP address through DNS, then retrieves network details such as ASN, network owner, country, and continent.
The extension is designed for fast and simple domain and IP lookups without unnecessary features.
We do not store any user history, searches, or personal information. The extension does not collect, store, or share user data. If you choose to provide an IPinfo API token, it is stored only locally in your Firefox profile so the extension can function, and it is not sent to us.
