Hostname of incoming apple push notification ? + iphone

any idea of the hostname that is sending the incoming push notification? The reason for this is because i have an iP开发者_JAVA技巧ad that uses a wifi connection to a network that have limited access so i would have to know the hostname to specifically allow the hostname to be able to connect and send the push notification. Im thinking that maybe it has something to do with aosnotify.mac.com

Do you know for a fact it's a problem? Because I haven't heard anywhere about having to set up special routing on the network for APNs to show up. I use NAT on my home network, and however Apple works to connect the device to their APN servers, it does just fine.
