How to have window update IP ranges.

I have considering a problem how to get window update IP ranges.

I could find window update URLs. However, our firewall could not using URL information.

It could use only IP that makes the problem.

Just I share window update URL.

 www.update.microsoft.com  
 update.microsoft.com  
 v5.windowsupdate.microsoft.com  
 download.windowsupdate.com  
 c.microsoft.com  
 windowsupdate.microsoft.com  
 v4.windowsupdate.microsoft.com  
 windowsupdate.com  
 ntservicepack.microsoft.com  
 wustat.windows.com  
 au.download.windowsupdate.com  
 updates.installshield.com  
 microsoft.com  
 urs.microsoft.com  
 go.microsoft.com  
 start.microsoft.com  
 crl.microsoft.com  
 catalog.update.microsoft.com  
 validation.sls.microsoft.com  
 na.activation.sls.microsoft.com  
 activation.sls.microsoft.com  
 sls.microsoft.com.nsatc.net

 activation.sls.microsoft.com.nsatc.net
