This hostname is part of TeamViewer's internal network, not a public website. You won't find a contact page or privacy policy because it's a router, not a business. The domain itself belongs to a well-known remote desktop company, and the SSL certificate is valid. Is br-rio-anx-r018.router.teamviewer.com a scam? No. It's a technical subdomain that isn't meant for browsing. For a legitimate infrastructure component, the signals are exactly what you'd expect: clean, secure, and unremarkable. There's no reason to treat it as a consumer-facing site or to worry about safety.
