DNS block for iOS update notifications

[jwojda]

I have a ticket open with apple, but they haven't called me yet. Does anybody know what IP/DNS I can block to prevent iOS devices from downloading iOS6 OTA?

we blocked gs.apple.com but apparently some devices are still getting updated.

Interesting... if you figure out a way to effectively prevent iOS updates by blocking a certain DNS, I'd really like to know.

-Thanks

Ditto. I'd like to know too!!

This is still relevant, so here you go. This appears to work. We'll know in a few minutes when Apple is supposed to be releasing iOS7.
