You can download the Azure Datacenter IP Ranges xml from the download center. Updates to this file happen frequently as new ranges are added. Note that the updated date on this page does not reflect the date the file is updated on the download center. The download center page will show the date that the file was updated. The list that you’ll download contains the Compute IP address ranges (including SQL ranges) used by the Azure Datacenters. Each section specifies the geographic region and the IP address ranges associated with that region. Do not assume that all traffic originating from these IP address ranges is trustworthy.
