See section IP Address Configuration for an example on how to configure a static IPv4 or IPv6 on a specific IntefaceInterface.
Dynamic IP Address Configuration On An Interface
IPv4 address can be configured dynamically on an inteface by integrating µC/DHCP-c DHCPc to your application.
If you want to develop your how network application to setup dynamic addressing, the IPv4 functions NetIPv4_CfgAddrAddDynamic(), NetIPv4_CfgAddrAddDynamicStart(), NetIPv4_CfgAddrAddDynamicStop() should be used.
Dynamic addressing address configuration is not yet availabe for IPv6.

You also have the option to bind to the wildcard adress (0.0.0.0 for IPv4 and :: for IPv6). In that case, the server socket is not bound to any IP address in particular, therefore any packets send to the corresponding server port number will be received by the server regardless of the destination address. When sending packets, the µC/TCP-IP stack will take charge care of setting the best source address for the destination.

If you don't bound to an IP address, the µC/TCP-IP stack will take charge care of setting the source address of packets to send.
