Configure IP address of Ethernet Audrino

Hello,

I would like to restart or discover the IP address of an Audrino ethernet - Chassis Manager that is within a ICARUS USRP node. However, I could not found the IP address that initially was configured for the chassis manager. I tested with nmap -sP IP/mask , arp -a and wireshark to discover the IP address without success. Hence, I looking up a manner to reset the Audrino ethernet to find out the first IP address that was configured on chassis manager.
If someone know something about, could comment, please?

Regards,
Jean

Well I'm not sure I understand the issue but it seems like you could just use Ethernet.localIP(): Ethernet - Arduino Reference.
