Is `https://api.github.com/repos/mcpfusion/core` allowed?

Yes, `api.github.com` is in the allowed domains list.

Check if `http://192.168.1.50:8080` is safe.

No, this request is blocked because 192.168.1.50 belongs to a private IP range.

Verify membership for `sub.mysite.org`.

The hostname `sub.mysite.org` is authorized as it matches the `mysite.org` suffix.

It blocks private IP ranges like 127.0.0.1 using bitwise math to ensure agents cannot access internal infrastructure.
