Yunbao VPNVPN describes a connection technology
A VPN commonly creates an encrypted tunnel between a device and a server for remote access or protecting part of network transport. It can serve private business networks or personal Internet access. Traffic coverage depends on the client and routing configuration.
Circumvention describes a purpose; ladder is informal
Circumvention describes reaching resources affected by network restrictions. The Chinese term ladder is an informal name for related tools, not a technical standard. Such tools may use VPNs, proxies or other forwarding methods. Local networks, servers and destinations still affect access.
What do proxy and node mean?
A forward proxy forwards requests for a client; the word proxy does not establish encryption. A node commonly means a server endpoint or route. Region labels, endpoint counts and signal icons alone do not establish end-to-end performance.
How to check the actual scope
- Check supported devices and the app download source.
- Read mode descriptions to identify covered apps and traffic.
- Compare your usual services on the same device and network.
- Read plan and privacy terms; connected does not mean every website works or complete anonymity.
