Renesas NetX Auto IP, NetX Duo Auto IP networking Application Note

NetX Auto IP and NetX Duo Auto IP are networking modules designed to dynamically configure IPv4 addresses on a local network without requiring a server. Auto IP uses address resolution protocol (ARP) for automatic IP address assignment and allocates addresses in the range of 169.254.1.0 through 169.254.254.255. This module guide provides information to effectively use this module with your own design, configure it correctly for the target application and write code using the included application project code as a reference and efficient starting point.
