I don't think that the exact problem is double counting IP addresses or multiple CDN shards that are basically the same but there are several concerning things: 1) Why would relatively specific services need to contact so many different endpoints? The skype service is using about 40 different endpoints by the look of it. 2) Why can't the providers of these services use much more consistent naming? I am less concerned about pipe.skype.com and avatar.skype.com being called from skype because it makes sense. On the other hand, calling b-ring.msedge.net is weird. What is that site? Could be MS, could be anything. 3) It is not clear whether these services were expected to be enabled or not. For example, I don't like the idea that Windows is wasting internet bandwidth on Cortana or XBox live since I use neither of them.
