How to check for an active Internet Connection on iPhone SDK?
I have to find to which network the ipad is currently connected through the ipad application. is it possible through the reachability code?
Do you mean the SSID of the wifi network?
That's not possible.
For checking internet/intranet connection, use the reachability, and specify your own server (on the intranet) or a public server (on the internet) to check if you can reach it.

Improve this question
I want to know the different options which are available in iOS to communicate between one to many devices.
For example, one iPhone or iPad acts as server and sends instructions to more than 100 iPads or iPhones.
Can I get some ideas or suggestions on this?
You can use TCP or UDP over a local WLAN.
It is quite easy. To discover the "Server"-device create a Bonjour Service on this device and search for the service with the client-devices
You can then retrieve the IP Address of the device and start communication.
This is the fastest and easiest solution. It has just one requirement, all Devices need to be in the same WLAN.
The additional bonus is that this layout is accessible for all devices having WLAN. So also Android, computers and all the other stuff available.
An optional way would be to do this over a dedicated server backend.
And every device keeps a opened stream to this server to get realtime updates.
Then you don't have the requirement that every device needs to be in the same WLAN. It could also access the Server via mobile network or whatever.
Bluetooth is no option because there are too many devices you want to handle.

How to capture iphone network packets ?
im using windows
is it possible to capture its packets through wifi ?
Use mitmproxy
You can set this up as a proxy server, and then set the proxy on your iPhone to this. You should be able to see all the traffic, included encrypted traffic. This is the program used to determine that Path was downloading the entire Contacts database for its users.
You can use WireShark or Cain & Abel. You would connect your phone to wifi and sniff the packets based on it's IP.
The way I do this with OS X is to set up an ad-hoc wifi network on my Mac, connect the phone to it and share my wired connection with the ad-hoc wifi network. Then I can capture on the wifi card's interface and see traffic going to the iPhone. Presumably you can do a similar thing with Windows.
You can use Paros to set a proxy on your computer and route your iPhone through that proxy. Paros will then show you all the requests being made through the proxy from you iPhone. There is a Step-By-Step guide here: Sniff your iPhones network traffic with Paros.
I was searching for the same thing and came across these similar questions:

The second link shows the Paros solution.
