Block apple app store
I would like to completely block the apple app store on ipads and ipods. I don't really want to use the restrictions that are on the devices. I want to use either the router or opendns. I have added albert.apple.com, appldnld.apple.com, apple.com, ax.itunes.apple.com, ess.apple.com, gs.apple.com, itunes.apple.com, mesu.apple.com, push.apple.com and www.itunes.com. Is there something i'm missing to fully block it.
