When you see a hostname like gb-lon-anx-r019.router.teamviewer.com, it looks technical because that's exactly what it is: a router address used by TeamViewer's internal network. It's not a store, a login page, or a service you'd interact with directly. The valid SSL certificate and clean blacklist status are reassuring, and the parent domain β TeamViewer β is a legitimate company with millions of users worldwide. The 404 error you get when visiting is likely just a misconfigured public route, not a sign of a scam. For an infrastructure subdomain, there's nothing here to raise concern. If you're checking whether it's safe, the answer is yes β there's no risk, no phishing, and no reason to treat it as suspicious.
