Microsoft Azure uses 24 prefixes for StorageMover.
Short answer
Microsoft Azure lists these prefixes under “StorageMover”. 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.
