How can I get the IP address of the machine that a stack is running on?
Open a datagram socket to a legal IP address. That does not have to be assigned. Then get the hostAddress of that socket. Then close it. The hostAddress will be what you want.
If the machine has more than one IP address, the address will be the one that would be used in trying to make the connection. For example, on a firewall, the machine might have both a public IP address for one adaptor and a private IP address for the LAN on another adaptor. Also, a single Ethernet LAN might have more than one IP address assigned to an adaptor on a machine (I use this for addressing both my network and instruments that come with a fixed IP address). And then there are dialups and VPNs and...
The cool part about the datagram method is that it is not intrusive. It does not try to do anything on the net.
If you want the IP address of the default adaptor, try "255.255.255.255". This does not always work; I forgot the constraints.
This method would not work at one time on OS X, but that was fixed.
