An IP address identifies a device or network on the internet; VPNs replace the public-facing IP websites see with the VPN server’s IP. If a feature sounds vague in marketing, look for measurable signals: audits, documentation, and testable settings. For most people, the biggest privacy win is shielding activity from local network observers and reducing ISP- level profiling. For business users, clear policy and least-privilege access reduce risk more than ‘always route everything everywhere.’ VPN Surf and Elite VPN guidance aims to keep the concept actionable, not just theoretical.
