DNS Roaming is a free open source DNS changer software for Windows to switch DNS based on rules. Here it can switch DNS when network adapter changes, network name changes, and when you are assigned a specific IP range. Ir runs in the background and wait for network or IP to change to apply the rules, It supports popular secure DNS servers already such as Cloudflare DNS, Google, Quad9, etc. But you can add a custom DNS server as well for it to switch.

You can define multiple DNS switching rules and it will work accordingly. It runs as a Windows service and offers a simple UI through system tray for configuration.
