do we have any detailed update or description for the network service tags Network Service tags - detailed description for AzureCloud, Internet & Azure UpdateDelivery.
the document link https://learn.microsoft.com/en-us/azure/virtual-network/service-tags-overview provides very minimal description and it would help to understand what these service tags will really help with. for example AzureCloud it says it includes as Azure DC Public IPs. can i presume it could be used to route the traffic for windows updates services also through Azure backbone network.

for Internet service tag it describes as - The IP address space that's outside the virtual network and reachable by the public internet. The address range includes the Azure-owned public IP address space. does this mean if we apply this in UDR, it would bypass traffic for 0.0.0.0/0 to none?

    @Amit Prakash dutta Thank you for reaching out to Microsoft Q&A.

    I understand that want more clarity regarding the IP address range that the service tags include.

    Regarding AzureCloud servicetag, it includes ALL public IP addresses from Azure. I do not think it can be used for windows updates as that may be going to IPs outside of Azure. You can always refer to this page for the Azure IP Ranges and Service Tage-Public Cloud.

    Regarding Internet Service Tag, if applied, it will override the 0.0.0.0/0 if traffic is going to the Public Internet. Hope this helps.

    Please let us know if you have any further questions/concerns. Thank you!
