Microsoft Azure uses 7 prefixes for WindowsVirtualDesktop.

Last updated 5 Nov 2026 from Microsoft Azure’s own list (file dated 2026-11-02 (change 425))

Short answer

Microsoft Azure lists these prefixes under “WindowsVirtualDesktop”. Microsoft publishes Azure’s ranges weekly as Service Tags: named groups such as AzureCloud, Storage, Sql or AzureFrontDoor.Frontend, each a list of prefixes. We import the global (non-regional) tags.
