i read,seen the Reachablility example in Apple’s website but still not quite sure about determining whether the iphone is connected to a wifi network/ or a pc(ipaddress). All i understand about that example is that you give it a address, and it checks how it is accessible either via wifi,WWAN or not reachable at all.

Could anyone shed some light on this? Im new to iPhone programming :\

What i want is to check whether the iPhone is connected to a particular ipaddress via wifi at that moment of time, like clicking a button and a UIAlertView shows “Not connected via wifi to “INSERT IPADDRESS HERE” “when its not connected. Am i making sense? lol.

    The IP address is just used for testing a connection through wi-fi or WWAN to another machine on the Internet. All the Reachability framework tells you is if your device is connected to a TCP/IP network via wi-fi networking, via WWAN (through your cell phone connection), or not connected at all. It does not tell you if your phone is connected to a Mac or PC through the dock connector cable.
