If you've come across rr4---sn-i3belnl7.googlevideo.com, you're probably wondering if it's legitimate. The short answer is yes, but not in the way you might think. This domain is a subdomain of googlevideo.com, which Google uses for its video delivery network. It's not a website you browse or buy from, so terms like "scam" or "fake" don't really apply here. The 404 error you see is by design, meaning this server is only meant to handle video data, not web pages.
For context, almost no infrastructure node like this will have an about page, privacy policy, or customer support. What matters is the ownership chain, and that's rock solid: the domain sits inside Google's ASN with a valid SSL certificate and no blacklists. If you're simply seeing this URL in your network logs or as a redirect, there's no reason for concern. It's just another cog in Google's massive video platform.
