    Hi @Eryao Wong

    Windows Update requires TCP port 80, 443, and 49152-65535.

    For Security issues the IP address for the Windows Update web site constantly changes and it is not a fixed address. Also, there is no official publication of the IP addresses. Instead, we suggest either allowing all outbound connections to http & https ports or defining the DNS addresses as permitted destinations for traffic via the firewall.

    Microsoft list only the URLs and WSUS to the following list of URLs:

    http://windowsupdate.microsoft.com

    http://*.windowsupdate.microsoft.com

    https://*.windowsupdate.microsoft.com

    http://*.update.microsoft.com

    https://*.update.microsoft.com

    http://*.windowsupdate.com

    http://download.windowsupdate.com

    https://download.microsoft.com

    http://*.download.windowsupdate.com

    http://wustat.windows.com

    http://ntservicepack.microsoft.com

    http://go.microsoft.com

    http://dl.delivery.mp.microsoft.com

    https://dl.delivery.mp.microsoft.com

    @Eryao Wong Thanka for your posting on Q&A. @SUNOJ KUMAR YELURU Thanks fro your sharing on this forum.

    I agree with learn2skills. The IP address is dynamic and we could also run the nslookup command to get the IP address:
