CDNs commonly serve their pages based on the geographical allocation of the ip addresses of the connecting user. You could use a proxy server for all your http requests but directed at a country that is nowhere close to where you are located. At the end of it, if the requests still head off towards those ip addresses, you'll know that something isn't quite right.

However, that was a while back. Now CDNs also serve contents such as updates, etc. So if you can corroborate the connection as a valid service for something like Apple updates, especially with real life users, then you can be sure that it is a valid request.
