Advanced Threat Protection C2/Generic-A

Question

Hello, 
 I am wondering if I am seeing false positives or not? Every machine in my network hit on an IP address today according to ATP. the IP address is 205.185.216.10. Some show as IpTables and others as AFCd. I checked the Advanced Threat Protection log and I do see the entries since 16:32. I also checked the Web Filtering Log and I see multiple entries there with that as the destinationIP. This is seeing the Windows Update application in there. Though when I do an IP lookup on it, it shows for Highwinds Network group. I have sent an email to abuse@hwng.net, and am preparing to send an email to Microsoft as it might be possible that Windows Update has been hijacked. 
 Just not sure if these are legitimate or not. Plus maybe someone else was seeing the same thing. 
 
 Thank You.
