Hello, this should be an easy question but I can't seem to find the answer after a few web searches. I'm trying to prevent people's phones from connecting to my wifi hotspot and proceeding to download 100mb of updates, at the same time allowing them to connect for general browsing. I'm wondering if app updates primarily come from play.google.com or another place as I can block domains on my router. Also wondering about where Iphone apps update from but I realize this isn't the place to ask. If the updates are coming from all over the place then it's probably not practical, but a few domains are easy enough to block.
Thanks!
