You're going to Jailbreak all the iPad's?
Ok, you work in the IT group. All you need to do is to block FB from your internet access.
Hope all your questions are that simple.
You beat me to it, again!
by far the simplest method
Question really is not that simple. Working in IT, Facebook website has already been blocked obviously for a while. However the app is still allowed access. Kees already gave best answer. Hope all of your answers are it that simple Bob.
We'll have to find out more.
If FB is getting access via your network and you say it's blocked, then they found a way around your block.
Time to work your firewall or whatever does that blocking.
You asked how it accesses and if you get the wifi only model, it uses your wifi. If your wifi allows FB access, then it will get it.
I have encountered IT staffers that can't accept their blocks have failed.
A Little More Research
We are using Endian Firewall and it has blocked the URL perfectly. However, the app uses a different route obviously. That is what the question was referring to. One can not access from the URL on the iPad only from the app.
I have encountered people who can't accept they don't really know what they are talking about.
Then it's time for monitoring software ...
on the other side of the firewall and see what ip-address is being used. Than block that.
You'll need a Facebook app and a quiet evening or weekend where nobody else uses the network.
That helped. URL blocks are ineffective.
Here's why. Because these can allow access by typing in the IP number, you'll have to block the IP as well.
I continue to find IT staff that don't want to change these things.
Sorry but I seem to have upset you. My background includes writing a router software back in the early 90's before we had routers as we see today. While I can talk about such things, I find it can upset folk.
IPs are covered as well
We have recorded all of the known IPs of Facebook and it still doesnt help.
Thanks for the idea Bob, sorry if I have seemed standoff-ish. This problem has been racking our brains, but I really do appreciate the help.
Then a test is needed.
We have to watch the log files. Sorry if this repeats former knowledge but here goes.
1. Clear all the logs of the router/firewalls.
2. Access FB with the device.
3. See what the DNS and logs show for what was accessed.
Add those new URL and IPs to the block lists.
Remember if these are the 3G cellular models I can't know that. This discussion is, so far about the wifi only models.
Use the iPads security
Why not go into the settings of the iPad, change the restrictions on the ability to use the app store, after you install everything you want them to need or use, and it will erase the app store app from the home screen and they won't be able to download the app. That doesn't solve the browser version of Facebook though.
Until the teachers go into settings and change it back
this needs to be done at the Router level
Another Possible Answer
I had this problem at home. Where my children were using iDevices to access facebook. I blocked all access to their specific IP addresses and saw blocks to strange IP addresses. They started with 0.0.
I am going to investigate further and will post again if I find anything out.
If you have a router/firewall that will let you block a subnet try blocking 0.0.1.0 to 0.0.255.255 not sure what then mask would be for that.
I think I have the answer
This thread is quite old, but in case anybody else is looking for the answer, I think I have it. The url for an ipad app is not the normal url you would use accessing over a browser. To find the url which the app uses, go to the Appstore on an iPad, search for the app in question (say, facebook), tap on the Action icon (Square with an arrow coming out of it) in the apps detail page and Tap on Copy Link in the available options. You can then paste somewhere to see what it is, and then enter that into your url blocker in the normal way. For facebook the url will be "https://appsto.re/gb/NuV-q.i" and blocking this will block an ipad on the network from accessing Facebook.
