    Hi @Neeranjan Shettar ,

    Welcome to the Microsoft Q&A Platform. Thank you for reaching out & I hope you are doing well.
    I understand that you would like to know where the IP 104.44.16.145(be-9-0.ibr02.pnq01.ntwk.msn.net) is physically located.

    The reason you are not able to see this IP/FQDN in Azure service tags is that it's technically not a part of Azure.
    It's a part of Microsoft's backbone network.

    Microsoft has certain services that are not dependent on Azure. For example, O365.
    The IP should belong to one of the Routers we use for forwarding the packets.

    Now, your observation is correct.

    • PNQ naming convention indicates Pune. So, the IP is located in the Pune region only.
    • However, you cannot classify this as "Central India", because it's not part of Azure as stated above.

    Please do let us know if you need more information on this.

    Cheers,
    Kapil

    Hi,

    You can download this json where you have all the Azure public IPs used in services. you can figure out which region this IP belongs to from here: https://www.microsoft.com/en-us/download/details.aspx?id=56519

    I couldn't find this IP from the json and hence I think it is not part of Azure service. From https://ipinfo.io/104.44.16.145 it looks like this IP is registered to US, Chicago location.
