IPv4 doesn't support dynamic addresses. There's another protocol called DHCP 
often used for that, which requires a DHCP client to broadcast a request and 
parse the reply. The DHCP client can then assign the server-delegated address 
to your interface, or pass the info to you for further decision-making. Linux 
itself *does* have a built-in DHCP client, but it's not usually used and 
almost always disabled at compile-time to save space.
