Microsoft Azure uses 121 prefixes for Marketplace.
Short answer
Microsoft Azure lists these prefixes under “Marketplace”. 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.
