Using Planisys DNS RPZ with ProtonVPN

Introduction

This section explains how to configure Proton VPN to use a Planisys DNS server with RPZ (Response Policy Zone) protection. This combination blocks ads, malware, and trackers at the DNS level. When integrated with the VPN, it adds an extra layer of security and improves browsing experience. Ideal for protecting mobile or corporate users while maintaining unified policies.

Requirements

  • Have an active Proton VPN account

  • Have the Proton VPN app installed (Windows, macOS, Linux, Android, or iOS)

  • Have the IP addresses of the Planisys RPZ DNS servers

Objective

Force the use of Planisys DNS from Proton VPN so that all browsing, even over VPN, is filtered through real-time security and ad-blocking policies.

Advantages

  • Blocks ads and trackers without installing browser extensions

  • Protection against malicious sites through DNS policies

  • Works across all browsers and system-wide apps

  • Allows applying centralized filtering policies

  • Some Proton VPN servers may enforce their own DNS settings. It is recommended to try different server locations if it does not work initially.

  • For greater control, it can be integrated with DoH or DoT for increased security.
