VuiZ Domain & Site Inspector

VuiZ Domain & Site Inspector helps you view technical information about domains and websites directly from your browser. The extension provides a convenient way to inspect domain registration details, HTTPS certificates, DNS configuration, email settings, IP addresses, and hosting infrastructure without switching between multiple tools. Domain Information View registrar information, registration and expiration dates, nameservers, and other WHOIS details. When you visit a subdomain, the extension can automatically identify the root domain for the lookup. Expiration information is displayed clearly to help you keep track of domain renewal dates. HTTPS Certificate Check the status and validity period of a website's security certificate. You can also view information about the certificate issuer, certificate subject, and supported domain names. DNS Configuration View available DNS information for a domain, including record values and cache lifetime information. Results can be filtered and individual values can be copied when needed for administration or troubleshooting. Email Configuration View the domain's mail server configuration and check email authentication mechanisms such as SPF and DMARC. When appropriate, the extension can use information from the root domain when inspecting a subdomain. IP and Hosting Information View the website's resolved IP address and related network information, including the network provider, ASN, IP range, and regional network authority. Additional Features VuiZ Domain & Site Inspector provides a context-menu option for quickly looking up a domain and a search field for manually inspecting another domain. The interface supports both English and Vietnamese. Privacy VuiZ Domain & Site Inspector is not designed to track your browsing history or collect your cookies. Lookup requests are sent to VuiZ.net services to provide technical information about domains and websites. Developed by VuiZ.net.
