Need Windows Update Servers IP Address Range to allow in firewall

Could anyone advise what IP Address range is used by windows update, we need to add these into our firewall to allow.

Thank You

When there is a firewall between the Windows Update agent and the Internet, the firewall might need to be configured to allow communication for the HTTP and HTTPS ports used for Windows Update. Windows Update agent uses port 80 for HTTP and port 443 for HTTPS to obtain updates.
If your organization does not allow the ports and protocols to be open to all addresses, you can restrict access to the following sites:

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
http://download.microsoft.com
http://*.download.windowsupdate.com
http://wustat.windows.com

I believe the IP could be subject to change, which is why they use these domains instead.
