Summary:
A new dedicated subnet, 40.64.144.0/20, will be implemented for Windows 365 RDP Reverse Connect traffic. Customers using IP addresses for connectivity must update their configurations to include this subnet. The FQDN *.wvd.microsoft.com and port TCP:443 remain unchanged. No action is needed for those using the FQDN or Azure Service tag directly.

Details:
Coming soon, we are implementing a change to the core TCP-based RDP traffic for Cloud PC connections. This traffic uses the wildcard fully qualified domain name (FQDN) *.wvd.microsoft.com, which is outlined in the documentation. While the FQDN remains unchanged, the underlying IP addresses associated with it will be updated.
