I reinstalled Windows on one of my computers today and while it was updating itself, I noticed that it was downloading from a server on a sonic.net host rather than Microsoft or one of its CDN providers. I was confused/disturbed, and called Sonic for help. I was told that the IP I was downloading from did resolve to a sonic.net address but that it belonged to Akamai. So, false alarm.
In case anyone else notices the same thing- the IP may not show an Akamai or Microsoft hostname on a reverse lookup but it's legit. No need to freak out like I was.
Also, the person who helped me on the phone deserves more thanks than I gave her on the phone. She was willing to investigate the issue even though it wasn't really a problem at all, just some weirdness I noticed.
