Click the Robtex icon to instantly see what Robtex knows about the website you are visiting:

• Resolved IP addresses (IPv4 and IPv6)
• Popularity rankings (Majestic, Tranco, Cloudflare Radar, Umbrella, Chrome UX Report)
• Blocklist and reputation flags (malware, phishing, sanctions and censorship lists)
• One click to the full Robtex analysis of the domain

Optional site safety indicator: if you enable it, the extension checks each site you visit and colors the toolbar icon — grey for unknown, blue for clean, red with a warning badge for flagged sites.

Robtex has provided free DNS and network research tools since 2003. The extension sends the hostname of the site being checked to robtex.com — by default only when you click the icon. No browsing data is stored or shared beyond that.
